Key Features

• 2.4 GHz RF transceiver supporting Bluetooth

Low Energy 5.3

• Arm®

Cortex®

-M33 with TrustZone®

, floating point

unit (FPU) and memory protection unit (MPU) for

application control and Bluetooth Low Energy

host stack

• To support security requirements, the MCX W23

also offers support for HASH, AES, RSA, ECC, UUID,

dynamic encrypt and decrypt of embedded flash

memory with the PRINCE engine, PUF based key

storage, secure boot and debug authentication.

• Real-time clock (RTC) clocked by the FRO_32k at

32.768 kHz with 1 s resolution enables operation in

the always-on power domain. Additionally, it also

supports all low-power modes with 1 ms resolution.

• Integrated flash memory with error code correction

enabling autonomous operation or operation with a

host microcontroller.
