The Arm® Cortex®-M33 is the first feature rich implementation of the Armv8-M architecture.
The Cortex-M33 was developed to address all embedded and IoT markets especially those that require efficient security or digital signal control. TrustZone for Armv8-M is the foundation of security for all embedded applications. The processor has many optional features including DSP, a coprocessor interface, memory protection units and a floating-point unit. The optional coprocessor interface opens the door for customisation and extensibility to further decrease the power consumption of the system in the presence of frequent compute intensive operations. The Cortex-M33 achieves an optimal blend between real time determinism, energy efficiency, software productivity and system security which opens the door for many new applications and opportunities across diverse markets.
