NXP Semiconductors MCX W72x Microcontrollers
NXP Semiconductors MCX W72x Microcontrollers offer a 96MHz Arm® Cortex®-M33 core combined with a multiprotocol radio subsystem supporting Matter®, Thread®, Zigbee®, and BLUETOOTH® LE.
With a dedicated core and memory, the independent radio subsystem offloads the main CPU, holding it for the primary application and enabling firmware updates to support future wireless standards. The NXP MCX W72x additionally provides advanced security with an integrated EdgeLock® Secure Enclave Core Profile, which will be supported by NXP's EdgeLock 2GO cloud services for credential sharing.
The NXP MCX W72x incorporates Bluetooth Channel Sounding capabilities, with a dedicated on-chip Localization Compute Engine to decrease ranging latency. The device includes additional memory for application-specific code, connectivity stacks, and over-the-air firmware updates. Furthermore, the radio subsystem can operate the whole Thread or Zigbee stack with the Bluetooth Low Energy stack. This feature ensures reliable wireless performance, as the radio's real-time activities run on a separate core from the application.
