NXP K32W061/41 Microcontrollers — Ultra Low Power Wiress MCU Supporting multiprotocol applications

The NXP K32W061/41 microcontroller portfolio is designed to power the next generation of ultra-low-current multiprotocol wireless devices, supporting Zigbee®® 3.0/Thread™™/IEEE 802.15.4, Bluetooth® Low Energy 5.0 and optional NFC. The K32W061 includes several low-power modes and ultra-low TX and RX power consumption, which enables devices powered by K32W061/41 to have extended battery life. With high RX sensitivity and configurable TX output power, K32W061/41 offers reliable and robust communications performance.

The NXP K32W061/41 is powered by an Arm® Cortex®-M4 MCU and with 640 KB on-board flash and 152 KB SRAM, has enough room and flexibility for complex applications and over-the-air (OTA) upgrade capability without external memory. The K32W061/41 microcontroller has a rich set of MCU peripherals and 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.
