The Arm® Cortex®-M0+ is the most energy-efficient Arm® processor available for embedded applications with design constraints. It features one of the smallest silicon footprint and minimal code size to allow developers to achieve 32-bit performance at 16 and 8-bit price points. The low gate count of the processor enables deployment in applications where simple functions are required.

The Cortex®-M0+ brings additional features to the Arm® Cortex®-M0, as well as performance improvements in the CPU (2.46 CoreMark®/MHz compared to 2.33 CoreMark® for the M0 core). Cortex®-M0+ integrates a Memory Protection Unit (MPU), a single cycle I/O interface and a Micro Trace Buffer (MTB).
