Cortex-M Series

Scalable and Low-Power Technology for any Embedded Market

The ARM® Cortex®-M processor family is an upwards compatible range of energy-efficient, easy to use processors designed to help developers meet the needs of tomorrow's embedded applications. Those demands include delivering more features at a lower cost, increasing connectivity, better code reuse and improved energy efficiency.

The Cortex-M family is optimized for cost and power sensitive MCU and mixed-signal devices for end applications such as smart metering, human interface devices, automotive and industrial control systems, white goods, consumer products and medical instrumentation.

More information on ARM embedded products and resources is available in the Embedded Group on ARM Connected Community.
