Cortex-M Series

Scalable and Low-Power Technology for all Embedded Applications

The ARM Cortex-M processor family is a range of scalable and compatible, energy efficient, easy to use processors designed to help developers meet the needs of tomorrow’s smart and connected 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 applications such as Internet of Things, connectivity, motor control, smart metering, human interface devices, automotive and industrial control systems, domestic household appliances, consumer products and medical instrumentation.

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