The MCX W23 is a family of devices. All devices are Arm Cortex®-M33 based wireless microcontrollers for embedded applications supporting Bluetooth Low Energy 5.3. It can be used to develop IoT solutions. MCX W23xA supports LV_SM mode. MCX W23xB supports HV_SM and XR_SM mode.
Building on NXP's strong history of providing industrial edge solutions, the MCX W series offers a wide operating temperature range from -40 °C to 125 °C.
The Arm Cortex-M33 provides a security foundation, offering isolation to protect valuable IP and data with Trust Zone technology. It simplifies the design and software development of digital signal control systems with the integrated digital signal processing (DSP) instructions. To support security requirements, the MCX W23 also offers support for SHA-1, SHA2-256, AES, RSA, ECC, UUID, dynamic encryption, and decryption of the flash data using a PRINCE engine, debug authentication, and TBSA-M compliance.
