Low-Power Microcontroller with TrustZone 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. Designed to meet the needs of tomorrow’s smart and connected embedded applications, Cortex-M23 is the smallest and lowest-power microcontroller with TrustZone security, making it the ideal processor for applications where software isolation and software security are required.

Features and Benefits
Build a Security Foundation

Bringing TrustZone security to even the smallest and lowest-powered devices, the Cortex-M23 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.

 Achieve Longer Battery Life

The Cortex-M23 allows developers to optimize power usage for specific applications with built-in, low-power features. With its three highly optimized low-power modes, the processor conserves energy to match processing demands.

Differentiate Your Product

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

Energy-harvesting wireless sensor nodes use ambient energy as a power source where batteries or cables are not viable. Superior energy efficiency and the built-in TrustZone security make Cortex-M23 the ideal processor for use in maintenance-free, energy-harvesting IoT nodes and smart sensors.
