Multi-Layered 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. Cortex-M35P is the first Armv8-M processor with tamper-resistance built in to bring physical security within reach of any IoT product. 

Features and Benefits
Build a Security Foundation

With TrustZone security, the Cortex-M35P 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.

Provide Physical Security 

Cortex-M35P adds physical resilience and system safety functions, such as lockstep, configurable parity, and observability, without compromising performance. Anti-tampering provides state-of-the-art security and prevents costly security breaches.

Add Functionality 

Reduce chip system cost with combined control and signal processing in the same processor. Cortex-M35P has the option of integrated digital signal processing (DSP), SIMD, and MAC instructions that simplify overall system design, software development, and debug.

Use Cases
Where Innovation and Ideas Come to Life 

Controllers are widely used in industrial applications. Cortex-M35P 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.
