Arm Cortex-M23
The Arm® Cortex® -M23 is the smallest and most energy-efficient implementation of the Armv8-M architecture.
The Cortex-M23 processor is a very compact, two-stage pipelined processor that supports the Armv8-M baseline instruction set. The Cortex-M23 with TrustZone security extension is the ideal processor for the most constrained embedded applications where security is a key requirement.
TrustZone technology for Armv8-M provides hardware-enforced isolation between the trusted and the untrusted resources on the Cortex-M23 based device, while maintaining the efficient exception handling and determinism that have been the hallmark of all Cortex-M processors.
