Nuvoton - NK-BEDM2351 - NuMaker-PFM-M2351 Development Board

Arm® Cortex®-M23 - The NuMaker-PFM-M2351 is a development board based on NuMicro®-M2351 microcontroller. Nuvoton NuMicro® M2351 secure microcontroller series is empowered by Arm® Cortex®-M23 core with TrustZone® for Armv8-M architecture, which elevates the traditional firmware security to the new level of robust software security. With the NuMaker-PFM-M2351 board, users can easily develop the secure application project. The left part of this board is the M2351 platform, including the target chip M2351KIAAE and the related onboard application parts and connectors.
