The MCX W71 Wireless Microcontroller features a 96 MHz Arm® Cortex®-M33 core coupled with a multiprotocol radio subsystem supporting Matter™, Thread®, Zigbee® and Bluetooth® Low Energy. The independent radio subsystem, with a dedicated core and memory, offloads the main CPU, preserving it for the primary application and allowing firmware updates to support future wireless standards. The MCX W71x also offers advanced security with an integrated EdgeLock® Secure Enclave Core Profile and will be supported by NXP's EdgeLock 2GO cloud services for credential sharing.
The MCX W71x family supports industrial and IoT devices as a single chip solution or by acting as a coprocessor in a hosted architecture.
