GENERAL DESCRIPTION
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
members of the Blackfin
®
family of products, incorporating the
Analog Devices, Inc./Intel Micro Signal Architecture (MSA).
Blackfin processors combine a dual-MAC state-of-the-art signal
processing engine, the advantages of a clean, orthogonal RISC-
like microprocessor instruction set, and single instruction, mul-
tiple data (SIMD) multimedia capabilities into a single
instruction set architecture.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
completely code and pin-compatible, differing only with respect
to their performance and on-chip memory. Specific perfor-
mance and memory configurations are shown in Table 1.
By integrating a rich set of industry-leading system peripherals
and memory, Blackfin processors are the platform of choice for
next generation applications that require RISC-like program-
mability, multimedia support, and leading-edge signal
processing in one integrated package.
PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. Blackfin processors are designed in a low
power and low voltage design methodology and feature
dynamic power management—the ability to vary both the volt-
age and frequency of operation to significantly lower overall
power consumption. Varying the voltage and frequency can
result in a substantial reduction in power consumption, com-
pared with just varying the frequency of operation. This
translates into longer battery life for portable appliances.
SYSTEM INTEGRATION
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are
highly integrated system-on-a-chip solutions for the next gener-
ation of digital communication and consumer multimedia
applications. By combining industry-standard interfaces with a
high performance signal processing core, users can develop
cost-effective solutions quickly without the need for costly
external components. The system peripherals include a UART
port, an SPI port, two serial ports (SPORTs), four general-pur-
pose timers (three with PWM capability), a real-time clock, a
watchdog timer, and a parallel peripheral interface.
PROCESSOR PERIPHERALS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors con-
tain a rich set of peripherals connected to the core via several
high bandwidth buses, providing flexibility in system configura-
tion as well as excellent overall system performance (see the
functional block diagram in Figure 1 on Page 1). The general-
purpose peripherals include functions such as UART, timers
with PWM (pulse-width modulation) and pulse measurement
capability, general-purpose I/O pins, a real-time clock, and a
watchdog timer. This set of functions satisfies a wide variety of
typical system support needs and is augmented by the system
expansion capabilities of the part. In addition to these general-
purpose peripherals, the processors contain high speed serial
and parallel ports for interfacing to a variety of audio, video, and
modem codec functions; an interrupt controller for flexible
management of interrupts from the on-chip peripherals or
external sources; and power management control functions to
tailor the performance and power characteristics of the proces-
sor and system to many application scenarios.
All of the peripherals, except for general-purpose I/O, real-time
clock, and timers, are supported by a flexible DMA structure.
There is also a separate memory DMA channel dedicated to
data transfers between the processor’s various memory spaces,
including external SDRAM and asynchronous memory. Multi-
ple on-chip buses running at up to 133 MHz provide enough
bandwidth to keep the processor core running along with activ-
ity on all of the on-chip and external peripherals.
The processors include an on-chip voltage regulator in support
of the processor’s dynamic power management capability. The
voltage regulator provides a range of core voltage levels from
V
DDEXT
. The voltage regulator can be bypassed at the user’s
discretion.

BLACKFIN PROCESSOR CORE
As shown in Figure 2 on Page 5, the Blackfin processor core
contains two 16-bit multipliers, two 40-bit accumulators, two
40-bit ALUs, four video ALUs, and a 40-bit shifter. The compu-
tation units process 8-bit, 16-bit, or 32-bit data from the
register file.
The compute register file contains eight 32-bit registers. When
performing compute operations on 16-bit operand data, the
register file operates as 16 independent 16-bit registers. All
operands for compute operations come from the multiported
register file and instruction constant fields.
Each MAC can perform a 16-bit by 16-bit multiply in each
cycle, accumulating the results into the 40-bit accumulators.
Signed and unsigned formats, rounding, and saturation are
supported.
The ALUs perform a traditional set of arithmetic and logical
operations on 16-bit or 32-bit data. In addition, many special
instructions are included to accelerate various signal processing
tasks. These include bit operations such as field extract and
population count, modulo 2
32
multiply, divide primitives, satu-
ration and rounding, and sign/exponent detection. The set of
video instructions includes byte alignment and packing opera-
tions, 16-bit and 8-bit adds with clipping, 8-bit average
operations, and 8-bit subtract/absolute value/accumulate (SAA)
operations. Also provided are the compare/select and vector
search instructions.
For certain instructions, two 16-bit ALU operations can be per-
formed simultaneously on register pairs (a 16-bit high half and
16-bit low half of a compute register). Quad 16-bit operations
are possible using the second ALU.
The 40-bit shifter can perform shifts and rotates and is used to
support normalization, field extract, and field deposit
instructions.
The program sequencer controls the flow of instruction execu-
tion, including instruction alignment and decoding. For
program flow control, the sequencer supports PC relative and
indirect conditional jumps (with static branch prediction), and
subroutine calls. Hardware is provided to support zero-over-
head looping. The architecture is fully interlocked, meaning that
the programmer need not manage the pipeline when executing
instructions with data dependencies.
The address arithmetic unit provides two addresses for simulta-
neous dual fetches from memory. It contains a multiported
register file consisting of four sets of 32-bit index, modify,
length, and base registers (for circular buffering), and eight
additional 32-bit pointer registers (for C-style indexed stack
manipulation).
Blackfin processors support a modified Harvard architecture in
combination with a hierarchical memory structure. Level 1 (L1)
memories are those that typically operate at the full processor
speed with little or no latency. At the L1 level, the instruction
memory holds instructions only. The two data memories hold
data, and a dedicated scratchpad data memory stores stack and
local variable information.
In addition, multiple L1 memory blocks are provided, offering a
configurable mix of SRAM and cache. The memory manage-
ment unit (MMU) provides memory protection for individual
tasks that may be operating on the core and can protect system
registers from unintended access.
The architecture provides three modes of operation: user mode,
supervisor mode, and emulation mode. User mode has
restricted access to certain system resources, thus providing a
protected software environment, while supervisor mode has
unrestricted access to the system and core resources.
The Blackfin processor instruction set has been optimized so
that 16-bit opcodes represent the most frequently used instruc-
tions, resulting in excellent compiled code density. Complex
DSP instructions are encoded into 32-bit opcodes, representing
fully featured multifunction instructions. Blackfin processors
support a limited multi-issue capability, where a 32-bit instruc-
tion can be issued in parallel with two 16-bit instructions,
allowing the programmer to use many of the core resources in a
single instruction cycle.
The Blackfin processor assembly language uses an algebraic syn-
tax for ease of coding and readability. The architecture has been
optimized for use in conjunction with the C/C++ compiler,
resulting in fast and efficient software implementations.
MEMORY ARCHITECTURE
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors view
memory as a single unified 4G byte address space, using 32-bit
addresses. All resources, including internal memory, external
memory, and I/O control registers, occupy separate sections of
this common address space. The memory portions of this
address space are arranged in a hierarchical structure to provide
a good cost/performance balance of some very fast, low latency
on-chip memory as cache or SRAM, and larger, lower cost and
performance off-chip memory systems. See Figure 3, Figure 4,
and Figure 5 on Page 6.
The L1 memory system is the primary highest performance
memory available to the Blackfin processor. The off-chip mem-
ory system, accessed through the external bus interface unit
(EBIU), provides expansion with SDRAM, flash memory, and
SRAM, optionally accessing up to 132M bytes of
physical memory.
The memory DMA controller provides high bandwidth data-
movement capability. It can perform block transfers of code or
data between the internal memory and the external
memory spaces.
Internal (On-Chip) Memory
The processors have three blocks of on-chip memory that pro-
vide high bandwidth access to the core.
The first block is the L1 instruction memory, consisting of up to
80K bytes SRAM, of which 16K bytes can be configured as a
four way set-associative cache. This memory is accessed at full
processor speed.
ADSP-BF531/ADSP-BF532/ADSP-BF533
Rev. I | Page 5 of 64 | August 2013
The second on-chip memory block is the L1 data memory, con-
sisting of one or two banks of up to 32K bytes. The memory
banks are configurable, offering both cache and SRAM func-
tionality. This memory block is accessed at full processor speed.
The third memory block is a 4K byte scratchpad SRAM, which
runs at the same speed as the L1 memories, but is only accessible
as data SRAM and cannot be configured as cache memory.
External (Off-Chip) Memory
External memory is accessed via the external bus interface unit
(EBIU). This 16-bit interface provides a glueless connection to a
bank of synchronous DRAM (SDRAM) as well as up to four
banks of asynchronous memory devices including flash,
EPROM, ROM, SRAM, and memory mapped I/O devices.
The PC133-compliant SDRAM controller can be programmed
to interface to up to 128M bytes of SDRAM. The SDRAM con-
troller allows one row to be open for each internal SDRAM
bank, for up to four internal SDRAM banks, improving overall
system performance.
The asynchronous memory controller can be programmed to
control up to four banks of devices with very flexible timing
parameters for a wide variety of devices. Each bank occupies a
1M byte segment regardless of the size of the devices used, so
that these banks are only contiguous if each is fully populated
with 1M byte of memory.
I/O Memory Space
Blackfin processors do not define a separate I/O space. All
resources are mapped through the flat 32-bit address space.
On-chip I/O devices have their control registers mapped into
memory mapped registers (MMRs) at addresses near the top of
the 4G byte address space. These are separated into two smaller
blocks, one containing the control MMRs for all core functions,
and the other containing the registers needed for setup and con-
trol of the on-chip peripherals outside of the core. The MMRs
are accessible only in supervisor mode and appear as reserved
space to on-chip peripherals.
Booting
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors con-
tain a small boot kernel, which configures the appropriate
peripheral for booting. If the processors are configured to boot
from boot ROM memory space, the processor starts executing
from the on-chip boot ROM. For more information, see Boot-
ing Modes on Page 14.

ADSP-BF531/ADSP-BF532/ADSP-BF533
Event Handling
The event controller on the processors handle all asynchronous
and synchronous events to the processor. The ADSP-BF531/
ADSP-BF532/ADSP-BF533 processors provide event handling
that supports both nesting and prioritization. Nesting allows
multiple event service routines to be active simultaneously. Pri-
oritization ensures that servicing of a higher priority event takes
precedence over servicing of a lower priority event. The control-
ler provides support for five different types of events:
Emulation – An emulation event causes the processor to
enter emulation mode, allowing command and control of
the processor via the JTAG interface.
Reset – This event resets the processor.
Nonmaskable Interrupt (NMI) – The NMI event can be
generated by the software watchdog timer or by the NMI
input signal to the processor. The NMI event is frequently
used as a power-down indicator to initiate an orderly shut-
down of the system.
Exceptions – Events that occur synchronously to program
flow (i.e., the exception is taken before the instruction is
allowed to complete). Conditions such as data alignment
violations and undefined instructions cause exceptions.
Interrupts – Events that occur asynchronously to program
flow. They are caused by input pins, timers, and other
peripherals, as well as by an explicit software instruction.

Each event type has an associated register to hold the return
address and an associated return-from-event instruction. When
an event is triggered, the state of the processor is saved on the
supervisor stack.
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors’ event
controller consists of two stages, the core event controller (CEC)
and the system interrupt controller (SIC). The core event con-
troller works with the system interrupt controller to prioritize
and control all system events. Conceptually, interrupts from the
peripherals enter into the SIC, and are then routed directly into
the general-purpose interrupts of the CEC.
Core Event Controller (CEC)
The CEC supports nine general-purpose interrupts (IVG157),
in addition to the dedicated interrupt and exception events. Of
these general-purpose interrupts, the two lowest priority inter-
rupts (IVG1514) are recommended to be reserved for software
interrupt handlers, leaving seven prioritized interrupt inputs to
support the peripherals of the processor. Table 2 describes the
inputs to the CEC, identifies their names in the event vector
table (EVT), and lists their priorities.
System Interrupt Controller (SIC)
The system interrupt controller provides the mapping and rout-
ing of events from the many peripheral interrupt sources to the
prioritized general-purpose interrupt inputs of the CEC.
Although the processors provide a default mapping, the user
can alter the mappings and priorities of interrupt events by writ-
ing the appropriate values into the interrupt assignment
registers (SIC_IARx). Table 3 describes the inputs into the SIC
and the default mappings into the CEC.
Event Control
The processors provide a very flexible mechanism to control the
processing of events. In the CEC, three registers are used to
coordinate and control events. Each register is 32 bits wide:
CEC interrupt latch register (ILAT) – The ILAT register
indicates when events have been latched. The appropriate
bit is set when the processor has latched the event and
cleared when the event has been accepted into the system.
This register is updated automatically by the controller, but
it can also be written to clear (cancel) latched events. This
register can be read while in supervisor mode and can only
be written while in supervisor mode when the correspond-
ing IMASK bit is cleared.
CEC interrupt mask register (IMASK) – The IMASK regis-
ter controls the masking and unmasking of individual
events. When a bit is set in the IMASK register, that event is
unmasked and is processed by the CEC when asserted. A
cleared bit in the IMASK register masks the event,
preventing the processor from servicing the event even
though the event may be latched in the ILAT register. This
register can be read or written while in supervisor mode.
Note that general-purpose interrupts can be globally
enabled and disabled with the STI and CLI instructions,
respectively.

ADSP-BF531/ADSP-BF532/ADSP-BF533
CEC interrupt pending register (IPEND) – The IPEND
register keeps track of all nested events. A set bit in the
IPEND register indicates the event is currently active or
nested at some level. This register is updated automatically
by the controller but can be read while in supervisor mode.
The SIC allows further control of event processing by providing
three 32-bit interrupt control and status registers. Each register
contains a bit corresponding to each of the peripheral interrupt
events shown in Table 3.
SIC interrupt mask register (SIC_IMASK) – This register
controls the masking and unmasking of each peripheral
interrupt event. When a bit is set in this register, that
peripheral event is unmasked and is processed by the sys-
tem when asserted. A cleared bit in this register masks the
peripheral event, preventing the processor from servicing
the event.
SIC interrupt status register (SIC_ISR) – As multiple
peripherals can be mapped to a single event, this register
allows the software to determine which peripheral event
source triggered the interrupt. A set bit indicates the
peripheral is asserting the interrupt, and a cleared bit indi-
cates the peripheral is not asserting the event.
SIC interrupt wakeup enable register (SIC_IWR) – By
enabling the corresponding bit in this register, a peripheral
can be configured to wake up the processor, should the
core be idled when the event is generated. See Dynamic
Power Management on Page 11.
Because multiple interrupt sources can map to a single general-
purpose interrupt, multiple pulse assertions can occur simulta-
neously, before or during interrupt processing for an interrupt
event already detected on this interrupt input. The IPEND reg-
ister contents are monitored by the SIC as the interrupt
acknowledgement.
The appropriate ILAT register bit is set when an interrupt rising
edge is detected (detection requires two core clock cycles). The
bit is cleared when the respective IPEND register bit is set. The
IPEND bit indicates that the event has entered into the proces-
sor pipeline. At this point the CEC recognizes and queues the
next rising edge event on the corresponding event input. The
minimum latency from the rising edge transition of the
general-purpose interrupt to the IPEND output asserted is three
core clock cycles; however, the latency can be much higher,
depending on the activity within and the state of the processor.
DMA CONTROLLERS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors have
multiple, independent DMA channels that support automated
data transfers with minimal overhead for the processor core.
DMA transfers can occur between the processor’s internal
memories and any of its DMA-capable peripherals. Addition-
ally, DMA transfers can be accomplished between any of the
DMA-capable peripherals and external devices connected to the
external memory interfaces, including the SDRAM controller
and the asynchronous memory controller. DMA-capable
peripherals include the SPORTs, SPI port, UART, and PPI. Each
individual DMA-capable peripheral has at least one dedicated
DMA channel.
The DMA controller supports both 1-dimensional (1-D) and 2-
dimensional (2-D) DMA transfers. DMA transfer initialization
can be implemented from registers or from sets of parameters
called descriptor blocks.
The 2-D DMA capability supports arbitrary row and column
sizes up to 64K elements by 64K elements, and arbitrary row
and column step sizes up to ±32K elements. Furthermore, the
column step size can be less than the row step size, allowing
implementation of interleaved data streams. This feature is
especially useful in video applications where data can be
de-interleaved on the fly.
Examples of DMA types supported by the DMA controller
include:
A single, linear buffer that stops upon completion
A circular, autorefreshing buffer that interrupts on each
full or fractionally full buffer
1-D or 2-D DMA using a linked list of descriptors
2-D DMA using an array of descriptors, specifying only the
base DMA address within a common page
In addition to the dedicated peripheral DMA channels, there are
two pairs of memory DMA channels provided for transfers
between the various memories of the processor system. This
enables transfers of blocks of data between any of the memo-
ries—including external SDRAM, ROM, SRAM, and flash
memory—with minimal processor intervention. Memory DMA
transfers can be controlled by a very flexible descriptor-based
methodology or by a standard register-based autobuffer
mechanism.
REAL-TIME CLOCK
The processor real-time clock (RTC) provides a robust set of
digital watch features, including current time, stopwatch, and
alarm. The RTC is clocked by a 32.768 kHz crystal external to
the ADSP-BF531/ADSP-BF532/ADSP-BF533 processors. The
RTC peripheral has dedicated power supply pins so that it can
remain powered up and clocked even when the rest of the pro-
cessor is in a low power state. The RTC provides several
programmable interrupt options, including interrupt per sec-
ond, minute, hour, or day clock ticks, interrupt on
programmable stopwatch countdown, or interrupt at a pro-
grammed alarm time.
The 32.768 kHz input clock frequency is divided down to a 1 Hz
signal by a prescaler. The counter function of the timer consists
of four counters: a 60 second counter, a 60 minute counter, a
24 hour counter, and a 32,768 day counter.
When enabled, the alarm function generates an interrupt when
the output of the timer matches the programmed value in the
alarm control register. The two alarms are time of day and a day
and time of that day.
ADSP-BF531/ADSP-BF532/ADSP-BF533
Rev. I | Page 9 of 64 | August 2013
The stopwatch function counts down from a programmed
value, with one second resolution. When the stopwatch is
enabled and the counter underflows, an interrupt is generated.
Like other peripherals, the RTC can wake up the processor from
sleep mode upon generation of any RTC wakeup event.
Additionally, an RTC wakeup event can wake up the processor
from deep sleep mode, and wake up the on-chip internal voltage
regulator from a powered-down state.
Connect RTC pins RTXI and RTXO with external components
as shown in Figure 6.
WATCHDOG TIMER
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors
include a 32-bit timer that can be used to implement a software
watchdog function. A software watchdog can improve system
availability by forcing the processor to a known state through
generation of a hardware reset, nonmaskable interrupt (NMI),
or general-purpose interrupt, if the timer expires before being
reset by software. The programmer initializes the count value of
the timer, enables the appropriate interrupt, then enables the
timer. Thereafter, the software must reload the counter before it
counts to zero from the programmed value. This protects the
system from remaining in an unknown state where software,
which would normally reset the timer, has stopped running due
to an external noise condition or software error.
If configured to generate a hardware reset, the watchdog timer
resets both the core and the processor peripherals. After a reset,
software can determine if the watchdog was the source of the
hardware reset by interrogating a status bit in the watchdog
timer control register.
The timer is clocked by the system clock (SCLK), at a maximum
frequency of f
SCLK
.
TIMERS
There are four general-purpose programmable timer units in
the ADSP-BF531/ADSP-BF532/ADSP-BF533 processors. Three
timers have an external pin that can be configured either as a
pulse-width modulator (PWM) or timer output, as an input to
clock the timer, or as a mechanism for measuring pulse widths
and periods of external events. These timers can be synchro-
nized to an external clock input to the PF1 pin (TACLK), an
external clock input to the PPI_CLK pin (TMRCLK), or to the
internal SCLK.
The timer units can be used in conjunction with the UART to
measure the width of the pulses in the data stream to provide an
autobaud detect function for a serial channel.
The timers can generate interrupts to the processor core provid-
ing periodic events for synchronization, either to the system
clock or to a count of external signals.
In addition to the three general-purpose programmable timers,
a fourth timer is also provided. This extra timer is clocked by the
internal processor clock and is typically used as a system tick
clock for generation of operating system periodic interrupts.
SERIAL PORTS (SPORTs)
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors
incorporate two dual-channel synchronous serial ports
(SPORT0 and SPORT1) for serial and multiprocessor commu-
nications. The SPORTs support the following features:
•I
2
S capable operation.
Bidirectional operation – Each SPORT has two sets of inde-
pendent transmit and receive pins, enabling eight channels
of I
2
S stereo audio.
Buffered (8-deep) transmit and receive ports – Each port
has a data register for transferring data words to and from
other processor components and shift registers for shifting
data in and out of the data registers.
Clocking – Each transmit and receive port can either use an
external serial clock or generate its own, in frequencies
ranging from (f
SCLK
/131,070) Hz to (f
SCLK
/2) Hz.
Word length – Each SPORT supports serial data words
from 3 bits to 32 bits in length, transferred most-signifi-
cant-bit first or least-significant-bit first.
Framing – Each transmit and receive port can run with or
without frame sync signals for each data word. Frame sync
signals can be generated internally or externally, active high
or low, and with either of two pulse widths and early or late
frame sync.
Companding in hardware – Each SPORT can perform
A-law or μ-law companding according to ITU recommen-
dation G.711. Companding can be selected on the transmit
and/or receive channel of the SPORT without additional
latencies.
DMA operations with single-cycle overhead Each SPORT
can automatically receive and transmit multiple buffers of
memory data. The processor can link or chain sequences of
DMA transfers between a SPORT and memory.

ADSP-BF531/ADSP-BF532/ADSP-BF533
Interrupts – Each transmit and receive port generates an
interrupt upon completing the transfer of a data-word or
after transferring an entire data buffer or buffers
through DMA.
Multichannel capability – Each SPORT supports 128 chan-
nels out of a 1,024-channel window and is compatible with
the H.100, H.110, MVIP-90, and HMVIP standards.
An additional 250 mV of SPORT input hysteresis can be
enabled by setting Bit 15 of the PLL_CTL register. When this bit
is set, all SPORT input pins have the increased hysteresis.
SERIAL PERIPHERAL INTERFACE (SPI) PORT
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors have
an SPI-compatible port that enables the processor to communi-
cate with multiple SPI-compatible devices.
The SPI interface uses three pins for transferring data: two data
pins (master output-slave input, MOSI, and master input-slave
output, MISO) and a clock pin (serial clock, SCK). An SPI chip
select input pin (SPISS) lets other SPI devices select the proces-
sor, and seven SPI chip select output pins (SPISEL7–1) let the
processor select other SPI devices. The SPI select pins are recon-
figured general-purpose I/O pins. Using these pins, the SPI port
provides a full-duplex, synchronous serial interface which sup-
ports both master/slave modes and multimaster environments.
The baud rate and clock phase/polarities for the SPI port are
programmable, and it has an integrated DMA controller, con-
figurable to support transmit or receive data streams. The SPI
DMA controller can only service unidirectional accesses at any
given time.
The SPI port clock rate is calculated as:
where the 16-bit SPI_BAUD register contains a value of 2 to
65,535.
During transfers, the SPI port simultaneously transmits and
receives by serially shifting data in and out on its two serial data
lines. The serial clock line synchronizes the shifting and sam-
pling of data on the two serial data lines.
UART PORT
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors pro-
vide a full-duplex universal asynchronous receiver/transmitter
(UART) port, which is fully compatible with PC-standard
UARTs. The UART port provides a simplified UART interface
to other peripherals or hosts, supporting full-duplex, DMA-sup-
ported, asynchronous transfers of serial data. The UART port
includes support for 5 data bits to 8 data bits, 1 stop bit or 2 stop
bits, and none, even, or odd parity. The UART port supports
two modes of operation:
PIO (programmed I/O) – The processor sends or receives
data by writing or reading I/O-mapped UART registers.
The data is double-buffered on both transmit and receive.
DMA (direct memory access) – The DMA controller trans-
fers both transmit and receive data. This reduces the
number and frequency of interrupts required to transfer
data to and from memory. The UART has two dedicated
DMA channels, one for transmit and one for receive. These
DMA channels have lower default priority than most DMA
channels because of their relatively low service rates.
The baud rate, serial data format, error code generation and sta-
tus, and interrupts for the UART port are programmable.
The UART programmable features include:
Supporting bit rates ranging from (f
SCLK
/1,048,576) bits per
second to (f
SCLK
/16) bits per second.
Supporting data formats from seven bits to 12 bits per
frame.
Both transmit and receive operations can be configured to
generate maskable interrupts to the processor.
The UART port’s clock rate is calculated as:
where the 16-bit UART_Divisor comes from the UART_DLH
register (most significant 8 bits) and UART_DLL register (least
significant 8 bits).
In conjunction with the general-purpose timer functions,
autobaud detection is supported.
The capabilities of the UART are further extended with support
for the Infrared Data Association (IrDA
®
) serial infrared physi-
cal layer link specification (SIR) protocol.
GENERAL-PURPOSE I/O PORT F
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors have
16 bidirectional, general-purpose I/O pins on Port F (PF15–0).
Each general-purpose I/O pin can be individually controlled by
manipulation of the GPIO control, status and interrupt
registers:
GPIO direction control register – Specifies the direction of
each individual PFx pin as input or output.
•GPIO control and status registers – The processor employs
a “write one to modify” mechanism that allows any combi-
nation of individual GPIO pins to be modified in a single
instruction, without affecting the level of any other GPIO
pins. Four control registers are provided. One register is
written in order to set GPIO pin values, one register is writ-
ten in order to clear GPIO pin values, one register is written
in order to toggle GPIO pin values, and one register is writ-
ten in order to specify GPIO pin values. Reading the GPIO
status register allows software to interrogate the sense of
the GPIO pin.
GPIO interrupt mask registers – The two GPIO interrupt
mask registers allow each individual PFx pin to function as
an interrupt to the processor. Similar to the two GPIO
control registers that are used to set and clear individual
GPIO pin values, one GPIO interrupt mask register sets
bits to enable interrupt function, and the other GPIO inter-
rupt mask register clears bits to disable interrupt function.

PFx pins defined as inputs can be configured to generate
hardware interrupts, while output PFx pins can be trig-
gered by software interrupts.
GPIO interrupt sensitivity registers – The two GPIO inter-
rupt sensitivity registers specify whether individual PFx
pins are level- or edge-sensitive and specify—if edge-sensi-
tive—whether just the rising edge or both the rising and
falling edges of the signal are significant. One register
selects the type of sensitivity, and one register selects which
edges are significant for edge-sensitivity.
PARALLEL PERIPHERAL INTERFACE
The processors provide a parallel peripheral interface (PPI) that
can connect directly to parallel ADCs and DACs, video encod-
ers and decoders, and other general-purpose peripherals. The
PPI consists of a dedicated input clock pin, up to three frame
synchronization pins, and up to 16 data pins. The input clock
supports parallel data rates up to half the system clock rate and
the synchronization signals can be configured as either inputs or
outputs.
The PPI supports a variety of general-purpose and ITU-R 656
modes of operation. In general-purpose mode, the PPI provides
half-duplex, bi-directional data transfer with up to 16 bits of
data. Up to three frame synchronization signals are also pro-
vided. In ITU-R 656 mode, the PPI provides half-duplex bi-
directional transfer of 8- or 10-bit video data. Additionally, on-
chip decode of embedded start-of-line (SOL) and start-of-field
(SOF) preamble packets is supported.
General-Purpose Mode Descriptions
The general-purpose modes of the PPI are intended to suit a
wide variety of data capture and transmission applications.
Three distinct sub modes are supported:
Input mode – Frame syncs and data are inputs into the PPI.
Frame capture mode – Frame syncs are outputs from the
PPI, but data are inputs.
Output mode – Frame syncs and data are outputs from the
PPI.
Input Mode
Input mode is intended for ADC applications, as well as video
communication with hardware signaling. In its simplest form,
PPI_FS1 is an external frame sync input that controls when to
read data. The PPI_DELAY MMR allows for a delay (in PPI_-
CLK cycles) between reception of this frame sync and the
initiation of data reads. The number of input data samples is
user programmable and defined by the contents of the
PPI_COUNT register. The PPI supports 8-bit and 10-bit
through 16-bit data, programmable in the PPI_CONTROL
register.
Frame Capture Mode
Frame capture mode allows the video source(s) to act as a slave
(e.g., for frame capture). The processors control when to read
from the video source(s). PPI_FS1 is an HSYNC output and
PPI_FS2 is a VSYNC output.
Output Mode
Output mode is used for transmitting video or other data with
up to three output frame syncs. Typically, a single frame sync is
appropriate for data converter applications, whereas two or
three frame syncs could be used for sending video with hard-
ware signaling.
ITU-R 656 Mode Descriptions
The ITU-R 656 modes of the PPI are intended to suit a wide
variety of video capture, processing, and transmission applica-
tions. Three distinct sub modes are supported:
•Active video only mode
Vertical blanking only mode
Entire field mode
Active Video Only Mode
Active video only mode is used when only the active video por-
tion of a field is of interest and not any of the blanking intervals.
The PPI does not read in any data between the end of active
video (EAV) and start of active video (SAV) preamble symbols,
or any data present during the vertical blanking intervals. In this
mode, the control byte sequences are not stored to memory;
they are filtered by the PPI. After synchronizing to the start of
Field 1, the PPI ignores incoming samples until it sees an SAV
code. The user specifies the number of active video lines per
frame (in PPI_COUNT register).
Vertical Blanking Interval Mode
In this mode, the PPI only transfers vertical blanking interval
(VBI) data.
Entire Field Mode
In this mode, the entire incoming bit stream is read in through
the PPI. This includes active video, control preamble sequences,
and ancillary data that can be embedded in horizontal and verti-
cal blanking intervals. Data transfer starts immediately after
synchronization to Field 1. Data is transferred to or from the
synchronous channels through eight DMA engines that work
autonomously from the processor core.
DYNAMIC POWER MANAGEMENT
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors pro-
vides four operating modes, each with a different performance/
power profile. In addition, dynamic power management pro-
vides the control functions to dynamically alter the processor
core supply voltage, further reducing power dissipation. Control
of clocking to each of the processor peripherals also reduces
power consumption. See Table 4 for a summary of the power
settings for each mode.
Full-On Operating Mode—Maximum Performance
In the full-on mode, the PLL is enabled and is not bypassed,
providing capability for maximum operational frequency. This
is the power-up default execution state in which maximum per-
formance can be achieved. The processor core and all enabled
peripherals run at full speed.
omm on Voom
Rev. I | Page 12 of 64 | August 2013
ADSP-BF531/ADSP-BF532/ADSP-BF533
Active Operating Mode—Moderate Power Savings
In the active mode, the PLL is enabled but bypassed. Because the
PLL is bypassed, the processor’s core clock (CCLK) and system
clock (SCLK) run at the input clock (CLKIN) frequency. DMA
access is available to appropriately configured L1 memories.
In the active mode, it is possible to disable the PLL through the
PLL control register (PLL_CTL). If disabled, the PLL must be
re-enabled before it can transition to the full-on or sleep modes.
Sleep Operating Mode—High Dynamic Power Savings
The sleep mode reduces dynamic power dissipation by disabling
the clock to the processor core (CCLK). The PLL and system
clock (SCLK), however, continue to operate in this mode. Typi-
cally an external event or RTC activity will wake up the
processor. When in the sleep mode, assertion of wakeup causes
the processor to sense the value of the BYPASS bit in the PLL
control register (PLL_CTL). If BYPASS is disabled, the proces-
sor will transition to the full-on mode. If BYPASS is enabled, the
processor will transition to the active mode.
When in the sleep mode, system DMA access to L1 memory is
not supported.
Deep Sleep Operating Mode—Maximum Dynamic Power
Savings
The deep sleep mode maximizes dynamic power savings by dis-
abling the clocks to the processor core (CCLK) and to all
synchronous peripherals (SCLK). Asynchronous peripherals,
such as the RTC, may still be running but cannot access internal
resources or external memory. This powered-down mode can
only be exited by assertion of the reset interrupt (RESET) or by
an asynchronous interrupt generated by the RTC. When in deep
sleep mode, an RTC asynchronous interrupt causes the proces-
sor to transition to the active mode. Assertion of RESET while
in deep sleep mode causes the processor to transition to the full-
on mode.
Hibernate State—Maximum Static Power Savings
The hibernate state maximizes static power savings by disabling
the voltage and clocks to the processor core (CCLK) and to all
the synchronous peripherals (SCLK). The internal voltage
regulator for the processor can be shut off by writing b#00 to
the FREQ bits of the VR_CTL register. In addition to disabling
the clocks, this sets the internal power supply voltage (V
DDINT
) to
0 V to provide the lowest static power dissipation. Any critical
information stored internally (memory contents, register con-
tents, etc.) must be written to a nonvolatile storage device prior
to removing power if the processor state is to be preserved.
Since V
DDEXT
is still supplied in this mode, all of the external
pins three-state, unless otherwise specified. This allows other
devices that may be connected to the processor to still have
power applied without drawing unwanted current. The internal
supply regulator can be woken up either by a real-time clock
wakeup or by asserting the RESET pin.
Power Savings
As shown in Table 5, the processors support three different
power domains. The use of multiple power domains maximizes
flexibility, while maintaining compliance with industry stan-
dards and conventions. By isolating the internal logic of the
processor into its own power domain, separate from the RTC
and other I/O, the processor can take advantage of dynamic
power management without affecting the RTC or other I/O
devices. There are no sequencing requirements for the various
power domains.
The power dissipated by a processor is largely a function of the
clock frequency of the processor and the square of the operating
voltage. For example, reducing the clock frequency by 25%
results in a 25% reduction in dynamic power dissipation, while
reducing the voltage by 25% reduces dynamic power dissipation
by more than 40%. Further, these power savings are additive, in
that if the clock frequency and supply voltage are both reduced,
the power savings can be dramatic.
The dynamic power management feature of the processor
allows both the processor’s input voltage (V
DDINT
) and clock fre-
quency (f
CCLK
) to be dynamically controlled.
The savings in power dissipation can be modeled using the
power savings factor and % power savings calculations.
The power savings factor is calculated as:

VOLTAGE REGULATION
The Blackfin processor provides an on-chip voltage regulator
that can generate appropriate V
DDINT
voltage levels from the
V
DDEXT
supply. See Operating Conditions on Page 20 for regula-
tor tolerances and acceptable V
DDEXT
ranges for specific models.
Figure 7 shows the typical external components required to
complete the power management system. The regulator con-
trols the internal logic voltage levels and is programmable with
the voltage regulator control register (VR_CTL) in increments
of 50 mV. To reduce standby power consumption, the internal
voltage regulator can be programmed to remove power to the
processor core while keeping I/O power (V
DDEXT
) supplied.
While in the hibernate state, I/O power is still being applied,
eliminating the need for external buffers. The voltage regulator
can be activated from this power-down state either through an
RTC wakeup or by asserting RESET, both of which initiate a
boot sequence. The regulator can also be disabled and bypassed
at the user’s discretion.
Voltage Regulator Layout Guidelines
Regulator external component placement, board routing, and
bypass capacitors all have a significant effect on noise injected
into the other analog circuits on-chip. The VROUT1–0 traces
and voltage regulator external components should be consid-
ered as noise sources when doing board layout and should not
be routed or placed near sensitive circuits or components on the
board. All internal and I/O power supplies should be well
bypassed with bypass capacitors placed as close to the proces-
sors as possible.
For further details on the on-chip voltage regulator and related
board design guidelines, see the Switching Regulator Design
Considerations for ADSP-BF533 Blackfin Processors (EE-228)
applications note on the Analog Devices web site (www.ana-
log.com)—use site search on “EE-228”.
CLOCK SIGNALS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors can
be clocked by an external crystal, a sine wave input, or a buff-
ered, shaped clock derived from an external clock oscillator.
If an external clock is used, it should be a TTL-compatible signal
and must not be halted, changed, or operated below the speci-
fied frequency during normal operation. This signal is
connected to the processor’s CLKIN pin. When an external
clock is used, the XTAL pin must be left unconnected.
Alternatively, because the processors include an on-chip oscilla-
tor circuit, an external crystal can be used. For fundamental
frequency operation, use the circuit shown in Figure 8.
A parallel-resonant, fundamental frequency, microprocessor-
grade crystal is connected across the CLKIN and XTAL pins.
The on-chip resistance between CLKIN and the XTAL pin is in
the 500 k range. Further parallel resistors are typically not rec-
ommended. The two capacitors and the series resistor shown in
Figure 8 fine tune the phase and amplitude of the sine fre-
quency. The capacitor and resistor values shown in Figure 8 are
typical values only. The capacitor values are dependent upon
the crystal manufacturer's load capacitance recommendations
and the physical PCB layout. The resistor value depends on the
drive level specified by the crystal manufacturer. System designs
should verify the customized values based on careful investiga-
tion on multiple devices over the allowed temperature range.
A third-overtone crystal can be used at frequencies above
25 MHz. The circuit is then modified to ensure crystal operation
only at the third overtone, by adding a tuned inductor circuit as
shown in Figure 8.

ADSP-BF531/ADSP-BF532/ADSP-BF533
As shown in Figure 9, the core clock (CCLK) and system
peripheral clock (SCLK) are derived from the input clock
(CLKIN) signal. An on-chip PLL is capable of multiplying the
CLKIN signal by a user programmable 0.5 to 64 multiplica-
tion factor (bounded by specified minimum and maximum
VCO frequencies). The default multiplier is 10, but it can be
modified by a software instruction sequence. On-the-fly
frequency changes can be effected by simply writing to the
PLL_DIV register.
All on-chip peripherals are clocked by the system clock (SCLK).
The system clock frequency is programmable by means of the
SSEL3–0 bits of the PLL_DIV register. The values programmed
into the SSEL fields define a divide ratio between the PLL output
(VCO) and the system clock. SCLK divider values are 1 through
15. Table 6 illustrates typical system clock ratios.
The maximum frequency of the system clock is f
SCLK
. The divi-
sor ratio must be chosen to limit the system clock frequency to
its maximum of f
SCLK
. The SSEL value can be changed dynami-
cally without any PLL lock latencies by writing the appropriate
values to the PLL divisor register (PLL_DIV). When the SSEL
value is changed, it affects all of the peripherals that derive their
clock signals from the SCLK signal.
The core clock (CCLK) frequency can also be dynamically
changed by means of the CSEL1–0 bits of the PLL_DIV register.
Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in
Table 7. This programmable core clock capability is useful for
fast core frequency modifications.
BOOTING MODES
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors have
two mechanisms (listed in Table 8) for automatically loading
internal L1 instruction memory after a reset. A third mode is
provided to execute from external memory, bypassing the boot
sequence.
The BMODE pins of the reset configuration register, sampled
during power-on resets and software-initiated resets, imple-
ment the following modes:
Execute from 16-bit external memory – Execution starts
from address 0x2000 0000 with 16-bit packing. The boot
ROM is bypassed in this mode. All configuration settings
are set for the slowest device possible (3-cycle hold time;
15-cycle R/W access times; 4-cycle setup).
Boot from 8-bit or 16-bit external flash memory – The flash
boot routine located in boot ROM memory space is set up
using asynchronous Memory Bank 0. All configuration set-
tings are set for the slowest device possible (3-cycle hold
time; 15-cycle R/W access times; 4-cycle setup).
Boot from SPI serial EEPROM/flash (8-, 16-, or 24-bit
addressable, or Atmel AT45DB041, AT45DB081, or
AT45DB161) – The SPI uses the PF2 output pin to select a
single SPI EEPROM/flash device, submits a read command
and successive address bytes (0x00) until a valid 8-, 16-, or
24-bit addressable EEPROM/flash device is detected, and
begins clocking data into the processor at the beginning of
L1 instruction memory.
Boot from SPI serial master – The Blackfin processor oper-
ates in SPI slave mode and is configured to receive the bytes
of the LDR file from an SPI host (master) agent. To hold off
the host device from transmitting while the boot ROM is
busy, the Blackfin processor asserts a GPIO pin, called host
wait (HWAIT), to signal the host device not to send any

more bytes until the flag is deasserted. The GPIO pin is
chosen by the user and this information is transferred to
the Blackfin processor via bits[10:5] of the FLAG header in
the LDR image.
For each of the boot modes, a 10-byte header is first read from
an external memory device. The header specifies the number of
bytes to be transferred and the memory destination address.
Multiple memory blocks can be loaded by any boot sequence.
Once all blocks are loaded, program execution commences from
the start of L1 instruction SRAM.
In addition, Bit 4 of the reset configuration register can be set by
application code to bypass the normal boot sequence during a
software reset. For this case, the processor jumps directly to the
beginning of L1 instruction memory.
INSTRUCTION SET DESCRIPTION
The Blackfin processor family assembly language instruction set
employs an algebraic syntax designed for ease of coding and
readability. The instructions have been specifically tuned to pro-
vide a flexible, densely encoded instruction set that compiles to
a very small final memory size. The instruction set also provides
fully featured multifunction instructions that allow the pro-
grammer to use many of the processor core resources in a single
instruction. Coupled with many features more often seen on
microcontrollers, this instruction set is very efficient when com-
piling C and C++ source code. In addition, the architecture
supports both user (algorithm/application code) and supervisor
(O/S kernel, device drivers, debuggers, ISRs) modes of opera-
tion, allowing multiple levels of access to core processor
resources.
The assembly language, which takes advantage of the proces-
sor’s unique architecture, offers the following advantages:
Seamlessly integrated DSP/CPU features are optimized for
both 8-bit and 16-bit operations.
A multi-issue load/store modified Harvard architecture,
which supports two 16-bit MAC or four 8-bit ALU + two
load/store + two pointer updates per cycle.
All registers, I/O, and memory are mapped into a unified
4G byte memory space, providing a simplified program-
ming model.
Microcontroller features, such as arbitrary bit and bit-field
manipulation, insertion, and extraction; integer operations
on 8-, 16-, and 32-bit data types; and separate user and
supervisor stack pointers.
Code density enhancements, which include intermixing of
16-bit and 32-bit instructions (no mode switching, no code
segregation). Frequently used instructions are encoded in
16 bits.
DEVELOPMENT TOOLS
Analog Devices supports its processors with a complete line of
software and hardware development tools, including integrated
development environments (which include CrossCore
®
Embed-
ded Studio and/or VisualDSP++
®
), evaluation products,
emulators, and a wide variety of software add-ins.
Integrated Development Environments (IDEs)
For C/C++ software writing and editing, code generation, and
debug support, Analog Devices offers two IDEs.
The newest IDE, CrossCore Embedded Studio, is based on the
Eclipse
TM
framework. Supporting most Analog Devices proces-
sor families, it is the IDE of choice for future processors,
including multicore devices. CrossCore Embedded Studio
seamlessly integrates available software add-ins to support real
time operating systems, file systems, TCP/IP stacks, USB stacks,
algorithmic software modules, and evaluation hardware board
support packages. For more information visit www.analog.com/
cces.
The other Analog Devices IDE, VisualDSP++, supports proces-
sor families introduced prior to the release of CrossCore
Embedded Studio. This IDE includes the Analog Devices VDK
real time operating system and an open source TCP/IP stack.
For more information visit www.analog.com/visualdsp. Note
that VisualDSP++ will not support future Analog Devices
processors.
EZ-KIT Lite Evaluation Board
For processor evaluation, Analog Devices provides wide range
of EZ-KIT Lite
®
evaluation boards. Including the processor and
key peripherals, the evaluation board also supports on-chip
emulation capabilities and other evaluation and development
features. Also available are various EZ-Extenders
®
, which are
daughter cards delivering additional specialized functionality,
including audio and video processing. For more information
visit www.analog.com and search on “ezkit” or “ezextender”.
EZ-KIT Lite Evaluation Kits
For a cost-effective way to learn more about developing with
Analog Devices processors, Analog Devices offer a range of EZ-
KIT Lite evaluation kits. Each evaluation kit includes an EZ-KIT
Lite evaluation board, directions for downloading an evaluation
version of the available IDE(s), a USB cable, and a power supply.
The USB controller on the EZ-KIT Lite board connects to the
USB port of the user’s PC, enabling the chosen IDE evaluation
suite to emulate the on-board processor in-circuit. This permits
the customer to download, execute, and debug programs for the
EZ-KIT Lite system. It also supports in-circuit programming of
the on-board Flash device to store user-specific boot code,
enabling standalone operation. With the full version of Cross-
Core Embedded Studio or VisualDSP++ installed (sold
separately), engineers can develop software for supported EZ-
KITs or any custom system utilizing supported Analog Devices
processors.
Software Add-Ins for CrossCore Embedded Studio
Analog Devices offers software add-ins which seamlessly inte-
grate with CrossCore Embedded Studio to extend its capabilities
and reduce development time. Add-ins include board support
packages for evaluation hardware, various middleware pack-
ages, and algorithmic modules. Documentation, help,
configuration dialogs, and coding examples present in these
add-ins are viewable through the CrossCore Embedded Studio
IDE once the add-in is installed.

Board Support Packages for Evaluation Hardware
Software support for the EZ-KIT Lite evaluation boards and EZ-
Extender daughter cards is provided by software add-ins called
Board Support Packages (BSPs). The BSPs contain the required
drivers, pertinent release notes, and select example code for the
given evaluation hardware. A download link for a specific BSP is
located on the web page for the associated EZ-KIT or EZ-
Extender product. The link is found in the Product Download
area of the product web page.
Middleware Packages
Analog Devices separately offers middleware add-ins such as
real time operating systems, file systems, USB stacks, and TCP/
IP stacks. For more information see the following web pages:

Algorithmic Modules
To speed development, Analog Devices offers add-ins that per-
form popular audio and video processing algorithms. These are
available for use with both CrossCore Embedded Studio and
VisualDSP++. For more information visit www.analog.com and
search on “Blackfin software modules” or “SHARC software
modules”.
Designing an Emulator-Compatible DSP Board (Target)
For embedded system test and debug, Analog Devices provides
a family of emulators. On each JTAG DSP, Analog Devices sup-
plies an IEEE 1149.1 JTAG Test Access Port (TAP). In-circuit
emulation is facilitated by use of this JTAG interface. The emu-
lator accesses the processor’s internal features via the
processor’s TAP, allowing the developer to load code, set break-
points, and view variables, memory, and registers. The
processor must be halted to send data and commands, but once
an operation is completed by the emulator, the DSP system is set
to run at full speed with no impact on system timing. The emu-
lators require the target board to include a header that supports
connection of the DSP’s JTAG port to the emulator.
For details on target board design issues including mechanical
layout, single processor connections, signal buffering, signal ter-
mination, and emulator pod logic, see the Engineer-to-Engineer
Note “Analog Devices JTAG Emulation Technical Reference
(EE-68) on the Analog Devices website (www.analog.com)—use
site search on “EE-68.” This document is updated regularly to
keep pace with improvements to emulator support.

RELATED SIGNAL CHAINS
A signal chain is a series of signal-conditioning electronic com-
ponents that receive input (data acquired from sampling either
real-time phenomena or from stored data) in tandem, with the
output of one portion of the chain supplying input to the next.
Signal chains are often used in signal processing applications to
gather and process data or to apply system controls based on
analysis of real-time phenomena. For more information about
this term and related topics, see the "signal chain" entry in
Wikipedia or the Glossary of EE Terms on the Analog Devices
website.

PIN DESCRIPTIONS
The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors pin
definitions are listed in Table 9.
All pins are three-stated during and immediately after reset,
except the memory interface, asynchronous memory control,
and synchronous memory control pins. These pins are all
driven high, with the exception of CLKOUT, which toggles at
the system clock rate. During hibernate, all outputs are three-
stated unless otherwise noted in Table 9.
If BR is active (whether or not RESET is asserted), the memory
pins are also three-stated. All unused I/O pins have their input
buffers disabled with the exception of the pins that need pull-
ups or pull-downs as noted in the table.
In order to maintain maximum functionality and reduce pack-
age size and pin count, some pins have dual, multiplexed
functionality. In cases where pin functionality is reconfigurable,
the default state is shown in plain text, while alternate function-
ality is shown in italics.

Rev. I | Page 23 of 64 | August 2013
System designers should refer to Estimating Power for the
ADSP-BF531/BF532/BF533 Blackfin Processors (EE-229), which
provides detailed information for optimizing designs for lowest
power. All topics discussed in this section are described in detail
in EE-229. Total power dissipation has two components:
1. Static, including leakage current
2. Dynamic, due to transistor switching characteristics
Many operating conditions can also affect power dissipation,
including temperature, voltage, operating frequency, and pro-
cessor activity. Electrical Characteristics on Page 22 shows the
current dissipation for internal circuitry (V
DDINT
). I
DDDEEPSLEEP
specifies static power dissipation as a function of voltage
(V
DDINT
) and temperature (see Table 14 or Table 15), and I
DDINT
specifies the total power specification for the listed test condi-
tions, including the dynamic component as a function of voltage
(V
DDINT
) and frequency (Table 17).
The dynamic component is also subject to an Activity Scaling
Factor (ASF) which represents application code running on the
processor (Table 16).
5
Applies to JTAG input pins (TCK, TDI, TMS, TRST).
6
Absolute value.
7
Applies to three-statable pins.
8
Applies to all signal pins.
9
Guaranteed, but not tested.
10
See the ADSP-BF533 Blackfin Processor Hardware Reference Manual for definitions of sleep, deep sleep, and hibernate operating modes.
11
See Table 16 for the list of I
DDINT
power vectors covered by various Activity Scaling Factors (ASF).

TEST CONDITIONS
All timing parameters appearing in this data sheet were mea-
sured under the conditions described in this section. Figure 45
shows the measurement point for ac measurements (except out-
put enable/disable). The measurement point V
MEAS
is 0.95 V for
V
DDEXT
(nominal) = 1.8 V or 1.5 V for V
DDEXT
(nominal) = 2.5 V/
3.3 V.
Output Enable Time Measurement
Output pins are considered to be enabled when they have made
a transition from a high impedance state to the point when they
start driving.
The output enable time t
ENA
is the interval from the point when
a reference signal reaches a high or low voltage level to the point
when the output starts driving as shown on the right side of
Figure 46.
The time t
ENA_MEASURED
is the interval, from when the reference
signal switches, to when the output voltage reaches V
TRIP
(high)
or V
TRIP
(low).
For V
DDEXT
(nominal) = 1.8 V—V
TRIP
(high) is 1.3 V and V
TRIP
(low) is 0.7 V.
For V
DDEXT
(nominal) = 2.5 V/3.3 V—V
TRIP
(high) is 2.0 V and
V
TRIP
(low) is 1.0 V.
Time t
TRIP
is the interval from when the output starts driving to
when the output reaches the V
TRIP
(high) or V
TRIP
(low) trip
voltage.
Time t
ENA
is calculated as shown in the equation:
If multiple pins (such as the data bus) are enabled, the measure-
ment value is that of the first pin to start driving.
Output Disable Time Measurement
Output pins are considered to be disabled when they stop driv-
ing, go into a high impedance state, and start to decay from their
output high or low voltage. The output disable time t
DIS
is the
difference between t
DIS_MEASURED
and t
DECAY
as shown on the left
side of Figure 45.
The time for the voltage on the bus to decay by V is dependent
on the capacitive load C
L
and the load current I
I
. This decay time
can be approximated by the equation:
The time t
DECAY
is calculated with test loads C
L
and I
L
, and with
V equal to 0.1 V for V
DDEXT
(nominal) = 1.8 V or 0.5 V for
V
DDEXT
(nominal) = 2.5 V/3.3 V.
The time t
DIS_MEASURED
is the interval from when the reference
signal switches, to when the output voltage decays V from the
measured output high or output low voltage.
Example System Hold Time Calculation
To determine the data output hold time in a particular system,
first calculate t
DECAY
using the equation given above. Choose V
to be the difference between the processor’s output voltage and
the input threshold for the device requiring the hold time. C
L
is
the total bus capacitance (per data line), and I
L
is the total leak-
age or three-state current (per data line). The hold time is t
DECAY
plus the various output disable times as specified in the Timing
Specifications on Page 27 (for example t
DSDAT
for an SDRAM
write cycle as shown in SDRAM Interface Timing on Page 30).

Capacitive Loading
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see Figure 47). V
LOAD
is 0.95 V for V
DDEXT
(nominal) = 1.8 V or 1.5 V for V
DDEXT
(nominal) =
2.5 V/3.3 V. Figure 48 through Figure 59 on Page 48 show how
output rise time varies with capacitance. The delay and hold
specifications given should be derated by a factor derived from
these figures. The graphs in these figures may not be linear out-
side the ranges shown.

NOTES:
THE WORST CASE TRANSMISSION LINE DELAY IS SHOWN AND CAN BE USED
FOR THE OUTPUT TIMING ANALYSIS TO REFELECT THE TRANSMISSION LINE
EFFECT AND MUST BE CONSIDERED. THE TRANSMISSION LINE (TD) IS FOR
LOAD ONLY AND DOES NOT AFFECT THE DATA SHEET TIMING SPECIFICATIONS.
ANALOG DEVICES RECOMMENDS USING THE IBIS MODEL TIMING FOR A GIVEN
SYSTEM REQUIREMENT. IF NECESSARY, A SYSTEM MAY INCORPORATE
EXTERNAL DRIVERS TO COMPENSATE FOR ANY TIMING DIFFERENCES.
