The Arm Cortex-M33 is the most configurable of all Cortex-M processors. It is a full featured microcontroller class processor based on the latest Arm v8-M architecture with Arm TrustZone security and digital signal processing. The Cortex-M33 provides all of the security benefits offered by TrustZone security isolation and is optimized for deterministic, real-time microcontroller class processor operations. The processor supports a large number of flexible configuration options to facilitate deployment in a wide range of diverse applications ranging from connected Bluetooth IoT nodes to smart motor controllers. It offers a dedicated co-processor interface to extend the capability of the processor for frequently used compute intensive operations. The Cortex-M33 delivers an optimal balance between performance, energy efficiency, security and productivity.


- Provide a security foundation, offering isolation to protect valuable IP and data with TrustZone technology - Extend the processor operation with the tightly coupled co-processor interface - Simplify the design and software development of digital signal control systems with the integrated digital signal processing (DSP) instructions - Accelerate single precision floating point math operations up to 10x over the equivalent integer software library with the optional floating point unit - Achieve industry-leading system energy efficiency using the integrated software controlled sleep modes, extensive clock gating and optional state retention
