These are small footprint cores with similar performance to the existing Cortex-M3/M4 processors.
Arm Cortex-M23 and Cortex-M33 are the first embedded processors based on the Armv8-M architecture, bringing Arm TrustZone to the most constrained IoT nodes.
Cortex-M33 features configuration options including a co-processor interface, DSP and floating point computation.
