The ARM Cortex®-M23 introduces the latest generation of the ARM Cortex-M product family. Based on the ARMv8-M baseline architecture, it is the smallest and most energy efficient ARM processor with ARM TrustZone® security technology. The Cortex-M23 is the ideal processor for constrained embedded applications requiring efficient security.
TrustZone for ARMv8-M provides hardware-enforced security isolation between trusted and the un-trusted resources on a Cortex-M23 based device, while maintaining the efficient exception handling and real-time determinism that is the hallmark for the Cortex-M family of processors.
The Cortex-M23 is a two-stage pipelined processor that is compact and ultra-efficient, yet supports the full ARMv8-M baseline instruction set. The processor is compatible with other processors in the Cortex-M family making software re-use a real cost-saving advantage.
