NXP Semiconductors K32W061 & K32W041 Wireless Microcontrollers

NXP Semiconductors K32W061 and K32W041 Wireless Microcontrollers (MCUs) are designed to power the next generation of ultra-low-current multiprotocol wireless devices, supporting Zigbee® 3.0, Thread, IEEE 802.15.4, and BLUETOOTH® Low Energy 5.0. The NXP K32W061 and K32W041 MCUs include several low-power modes and ultra-low Tx and Rx power consumption, making them ideal for battery-powered devices. With high Rx sensitivity and configurable Tx output power, the K32W061 and K32W041 MCUs offer reliable and robust communications performance.

The K32W061 and K32W041 are powered by an Arm® Cortex®-M4 core and with 640KB onboard flash and 152KB SRAM, have enough room and flexibility for complex applications, and Over-the-Air (OTA) upgrade capability without external memory. These MCUs have a rich set of peripherals, multiple serial communication interfaces for embedded connected applications, and a quad serial flash memory controller, SPIFI, that can be used to extend non-volatile memory.

NFC Option

The K32W061 MCU includes an integrated Near-Field Communication (NFC) NTAG IC to implement contactless NFC commissioning, simplifying network build-out while saving energy and increasing safety for the designer and end consumers.
