Tiny, 32-bit Processor

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 for smart and connected embedded applications, especially where size matters, the Cortex-M0 is the smallest Arm processor available, making it ideal for use in simple, cost-sensitive devices. For silicon designs, Arm Flexible Access offers the Cortex-M0 at $0.

Features and Benefits

Reduce Cost and Power

The exceptional code density of the Cortex-M0 significantly reduces memory requirements, which optimizes the use of on-chip Flash memory to save memory cost, reduce power, and increase performance. Take advantage of 32-bit processing intelligence at an 8/16-bit processor cost point.

Longer Battery Life

The Cortex-M0 processor 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.

Add Intelligence

The tiny footprint and extremely low-power requirements of Cortex-M0 mean that it can add intelligence to even the simplest of devices.

Information on Cortex-M0.


The Cortex-M0 has an exceptionally small silicon area, low power and minimal code footprint, enabling developers to achieve 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices. The ultra-low gate count of the processor enables its deployment in analog and mixed signal devices.
