ARM launches their first ARM Cortex-M processors based on ARMv8-M architecture with ARM TrustZone technology,
IoT subsystem with ARM CoreLink system IP for fastest, lowest-risk path to silicon, Secure SoC designs fortified by TrustZone CryptoCell technology, Complete wireless solution with ARM Cordio radio IP for 802.15.4 and Bluetooth 5, Cloud-based service for secure management of IoT devices via ARM mbed Cloud, Optimized implementation on ARM Artisan IoT POP IP for the TSMC 40ULP process.

ARM Cortex-M23 and Cortex-M33 are the first embedded processors based on the ARMv8-M architecture, bringing the proven secure foundation of ARM TrustZone to the most constrained IoT nodes. The majority of the top ten global MCU suppliers have already licensed one or both processors. Lead partners include Analog Devices, Microchip, Nuvoton, NXP, Renesas, Silicon Labs and STMicroelectronics.

The highly versatile Cortex-M33 features configuration options including a coprocessor interface, DSP and floating point computation, with increased performance and efficiency relative to Cortex-M3 and Cortex-M4. The Cortex-M23 takes security to the most constrained devices, building on the standard set by Cortex-M0+ as an ultra-low power microprocessor in a tiny footprint
The new Cortex-M processors are backwards compatible with ARMv6-M and ARMv7-M architectures for direct and fast porting, accelerating product development. TrustZone CryptoCell-312 fortifies the SoC with a rich set of security features protecting the authenticity, integrity and confidentiality of code and data.
