M2351 Series

The series of NuMicro Family 32-bit microcontrollers based on the ARM Cortex-M23 core, and empowered by the ARM TrustZone technology for ARMv8-M architecture to enhance the traditional firmware security to a new level of robust software security. They have security features that have been Arm® PSA Certified™ Level 1, Level 2 and PSA Functional API Certified. With TrustZone technology implemented, memory and peripherals could be divided into secure and non-secure regions to achieve data integrity, firmware update, and operation security. These microcontrollers are mainly designed to realize robust IoT security applications.
All Ics are RoHS compliant.

* Status: P - mass production, S - samples, UD - under development, N - not recommended for new design.
