NXP launches K32W061/41 wireless MCUs on Apr 30, 2020

  image

The K32W061/41 portfolio 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 K32W061/41 to have extended battery life. With high RX sensitivity and configurable TX output power, K32W061/41 offers reliable and robust communications performance.

K32W061/41 is powered by an ArmRegistered CortexRegistered-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. It 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.

Programmable(P)

A device that is compatible with more than one protocol. Device is programmed at manufacturing and can be reprogrammed by customer for another protocol.

Switched(S)

Only one stack connection maintained. Switching between protocols by using a bootloader.

Dynamic(D)

  Two stack connections maintained, the application time-slices between two protocols (can transmit and receive simultaneously for 15.4 and BLE).

 

Accelerate Your Time to Market

The K32W061/41 Development Kit (PN: IOTZTB-DK006) is designed to make it as easy as possible to get started with your project based on K32W061/41.
