K32W061/41 Connectivity MCUs

NXP's MCU features an Arm® Cortex®-M4 core which can easily handle network stacks and applications

Image of NXP's K32W061/41 Connectivity MCUsNXP's K32W061/41 series of MCUs is designed to power the next generation of ultra-low-current multiprotocol wireless devices, supporting Zigbee®3.0, Thread 1.1, IEEE 802.15.4, and Bluetooth® low energy 5.0. It includes several low-power modes and ultra-low TX and RX power consumption, providing extended battery life to devices powered by the K32W061/41. With its high RX sensitivity and configurable TX output power, the K32W061/41 offers reliable and robust communications performance.

NXP's K32W061/41 is powered by an Arm Cortex-M4 MCU. With 640 KB of on-board Flash and 152 KB SRAM, it has enough room and flexibility for complex applications and over-the-air (OTA) upgrade capability without using external memory. It has a rich set of MCU peripherals and multiple serial communication interfaces for embedded connected applications as well as a quad serial Flash memory controller (SPIFI) that can be used to extend non-volatile memory.
