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.
