MCX W Series Microcontrollers
MCX W series are secure, wireless MCUs designed to enable more compact, scalable and innovative designs for the next generation of smart and secure connected devices. The MCX W series, based on the Arm® Cortex®-M33, offers a unified range of pin-compatible multiprotocol wireless MCUs for Matter™, Thread®, Bluetooth® Low Energy and Zigbee®. MCX W enables interoperable and innovative smart home devices, building automation sensors, health IoT sensors and controls and smart energy products. The MCX W series is supported by MCUXpresso Developer Experience.
Key Features
Single MCU Platform
MCX W brings wireless to the MCX microcontroller portfolio by offering an MCU platform with a common core, architecture, intelligent peripherals and developer experience, all supported by the FRDM platform.
IoT Security
The MCX W series are part of NXP's Edgelock® Assurance program. The MCX W7 series integrates NXPs EdgeLock Secure Enclave Core Profile and offers support for NXP's Edgelock 2GO key and certificate management service.
Robust Wireless Performance
With an upgradable, dedicated radio subsystem, the MCX W7 series is built to support Matter, Thread, Zigbee and Bluetooth LE.

I need a single chip node that ships on Matter today and supports BLE provisioning and Thread/Zigbee, without adding a second radio. What’s the cleanest path?
Use MCX W71 or MCX W72, which integrate a dedicated upgradable radio subsystem supporting Matter over Thread, Zigbee and Bluetooth LE on one MCU with EdgeLock security and MCUXpresso support. Start with BLE onboarding, enable Thread/Matter in firmware as needed, and maintain PCB and pinout stability across W7 parts.
For precise indoor ranging like asset tags or access, can I use BLE channel sounding without switching to a separate UWB SoC and still manage battery life?
Choose MCX W72. It adds Bluetooth LE with channel sounding on the same Cortex M33 platform, letting you prototype ranging alongside standard BLE roles while keeping Matter, Thread and Zigbee options. The radio subsystem handles complexity; application code runs on M33 in compact QFN packages.
I'm building a low cost beacon or sensor that fits coin cell power and a small PCB footprint. Provision over BLE now, add sensors later if needed. What's the leanest option?
MCX W23x is a Bluetooth LE MCU for compact battery powered devices with modular sensor expansion, available in QFN40 5×5 mm and WLCSP. It includes a simple BLE stack and MCUXpresso examples for fast bring up, and lets you add sensors or features without changing the radio.
Time to first demo matters. What gets me to fast bring up for provisioning, multiprotocol testing and security without fragmented toolchains?
Use FRDM-MCXW71 for MCX W71, FRDM-MCXW72 for MCX W72, and FRDM-MCXW23 for MCX W23x. All connect to the MCUXpresso Developer Experience with IDE, SDK, drivers and examples plus EdgeLock enablement. You get ready projects for BLE, Thread, Zigbee, Matter and provisioning to measure throughput, current and latency on day one.
