The Ideal Blend of Real-Time Determinism, Efficiency, and Security

The Cortex-M processor series is designed to enable developers to create cost-sensitive and power-constrained solutions for a broad range of devices. Optimized for cost and power-sensitive microcontroller and mixed-signal applications, the Cortex-M33 processor is designed to address embedded and Internet of Things (IoT) markets, especially those that require efficient security or digital signal control. 

Features and Benefits
Build a Security Foundation

With TrustZone security, the Cortex-M33 processor enables programmers to use a familiar programming model to more easily achieve software isolation and create the foundation of security required for today’s IoT and embedded devices. Cortex-M33 offers the perfect balance between performance and efficiency with trusted execution. 

Add Floating Point and  DSP 

Reduce chip system cost with combined control and signal processing in the same processor. Cortex-M33 has the option of integrated Digital Signal Processing (DSP), SIMD, and MAC instructions that simplify overall system design, software development, and debug. Cortex-M33 simplifies signal processing, reduces development effort, and brings DSP with security to the masses.

Differentiate Your Product with Software Isolation 

System designers can now add valuable software and algorithms for further functionality in their products with the knowledge that they are protected with TrustZone software isolation. Trusted execution is now achievable, even in the most constrained embedded devices.

Use Cases
Where Innovation and Ideas Come to Life 

Controllers are widely used in industrial applications. Cortex-M33 comes equipped with essential microcontroller features, including low latency interrupt handling, integrated sleep modes, and debug and trace capabilities, making it the ideal processor for industrial control.
