ARM Cortex-M23 MCUs

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.

Arm® Platform Security Architecture ( PSA ) Support

The Platform Security Architecture ( PSA ) is a holistic set of threat models, security analyses, hardware and firmware architecture specifications, and an open source firmware reference implementation. PSA is a contribution from Arm to the entire IoT ecosystem, offering common ground rules and a more economical approach to building more secure devices, which ideally works with the TrustZone technology for Armv8-M.

 

To support Arm® PSA for better implementation of IoT security technology, Nuvoton has developed the Nuvoton Secure Microcontroller Platform ( NuSMP ) . The NuSMP is a mixture of hardware and software technology to help users meet up with the vast security requirements of general purpose and secure IoT microcontrollers. With the NuSMP, developers can easily achieve the secure services with M2351 Series microcontroller in coverage of: Trusted Boot ( Root of Trust ) , Secure OTA ( Over-The-Air ) firmware update ( including secure software download ) , Power management APIs for non-secure world and PC side crypto related development software tool. Nuvoton offers application note, sample code and training videos for each technology for developers’ access and reference.
