The ARM Cortex-M3 processor is a low-power processor that features low gate count, low interrupt latency, and low-cost debug. It is intended for deeply embedded applications that require fast interrupt response, including microcontrollers and automotive and industrial control systems. The ARM Cortex-M3 processor implements the ARMv7-M architecture profile.
