NXP MCX W Series of Wireless Microcontrollers (MCUs)

Smart, secure MCUs enable more compact, scalable and innovative designs

Geared for the next generation of smart and secure connected devices, NXP features their MCX W Series of Wireless Microcontrollers (MCUs). They offer a unified range of pin-compatible multiprotocol wireless MCUs for Matter, Thread, Bluetooth Low Energy and Zigbee.

Based on the Arm® Cortex®-M33, the MCX W series enables interoperable and innovative smart home devices, building automation sensors and controls and smart energy products.

The first two families in the MCX W series, the MCX W71x and W72x, maximize flexibility with a software upgradeable independent radio subsystem. With scalable memory sizes the MCX W series allows devices to be upgraded over time as user needs change and connectivity protocols like Matter continue to evolve.

Industry’s first wireless MCU to support the new Bluetooth® Channel Sounding standard
The MCX W series includes the MCX W72x, the industry’s first wireless MCU to support the new Bluetooth® Channel Sounding standard, which improves the accuracy and security of distance measurement compared to traditional Bluetooth technology. This is supported by NXP’s Localization Compute Engine (LCE) to reduce latency. Along with NXP’s Trimension® portfolio of ultra-wideband (UWB) secure radar and fine ranging products, the MCX W evolves ambient computing into a broad range applications.
