Image of NXP's K32W041AM and K32W041A Wireless MCUs NXP's K32W041AM/A expands their existing K32W0x portfolio which is 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. It includes several low-power modes and ultra-low TX and RX power consumption which enables devices powered by K32W0x to have extended battery life. With high RX sensitivity and configurable TX output power, K32W0x offers reliable and robust communications performance.

K32W0x is powered by an Arm® Cortex®-M4 MCU with 640 KB onboard Flash and 152 KB SRAM. It has enough room and flexibility for complex applications and over-the-air (OTA) upgrade capability without external memory. It has a rich set of MCU peripherals, multiple serial communication interfaces for embedded connected applications, and a quad serial Flash memory controller (SPIFI) that can be used to extend nonvolatile memory.

The K32W041A increases output power to +15 dBm. The K32W041AM also supports +15 dBm and includes an additional 1 MB of data Flash.

The K32W0x development kit is designed to make it as easy as possible to get started with Zigbee, Thread, and BLE projects based on K32W0x. The IOTZTB development kit’s rich components include a control bridge/generic router with an NFC reader, generic switch node, light/sensor node, USB dongle, and K32W061 and JN5189 upgrade boards that make quick prototyping possible for a small wireless network. K32W041AM and K32W041A upgrade boards are available separately.
