ARM Cortex-M23 MCU’s

NuMicro® M23 Family
– the TrustZone® empowered Cortex®-M23 based secure microcontrollers focusing on IoT security.

Cortex®-M23 CPU Core Based with TrustZone for Armv8-M

The NuMicro® M23 Family is based on the Arm® Cortex®-M23 core and is empowered by the Arm® TrustZone® for Arm®v8-M architecture. The NuMicro® M2351 series is the first series in the Family to realize robust IoT security applications.

With TrustZone® implemented, memory and peripherals could be divided into secure and non-secure worlds to achieve data integrity, firmware update, and operation security. In addition, TrustZone® for Arm®v8-M provides the key benefit of context switching between secure and non-secure worlds by hardware for faster transitions and greater power efficiency.
