STM32® 32-bit MCU Family

Leading supplier of ARM® Cortex®-M microcontrollers

STM32F7 Series of very High-Performance MCUs with ARM® Cortex®-M7 Core

Taking advantage of STMicroelectronics' ART Accelerator™ as well as an L1 cache, STM32F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at 216 MHz fCPU.

Smart architecture with new peripheral set
The STM32F7 series unleashes the new Cortex-M7 core:

  • AXI and multi-AHB bus matrix for interconnecting core, peripherals and memories
  • Two general-purpose DMA controllers and dedicated DMAs for Ethernet, high-speed USB On-The-Go interface and the Chrom-ART graphic accelerator.
  • Peripheral speed independent from CPU speed (dual clock support) allowing system clock changes without any impact on peripheral operations
  • Even more peripherals, such as two serial audio interfaces (SAI) with SPDIF output support, three I²S half-duplex with SPDIF input support, two USB OTG with dedicated power supply and Dual-mode QuadSPI Flash
  • Large SRAM with a scattered architecture:
    • 320 Kbytes of universal data memory, including 64 Kbytes of Tightly-Coupled Memory for Data (DTCM) for time critical data handling (stack, heap...)
    • 16 Kbytes of Tightly-Coupled Memory for Instructions (ITCM) for time-critical routines
    • 4 Kbytes of backup SRAM to keep data in the lowest power modes
