The exceptionally small silicon area, low power and minimal code footprint of the processor enables 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 Cortex-M0 processor also enables its deployment in analog and mixed signal devices. ARM DesignStart provides the fastest, simplest, no-risk route to custom silicon success. Get free access to design and license the Cortex-M0 and free forum support to accelerate custom SoC development.

Wearable Health Monitors
The Cortex-M0 processor can be incorporated into a SoC using a broad range of ARM technology including System IP, and Physical IP. It is fully supported by ARM development tools. Related IP includes:
Exceptional code density
On average, the mix between 16bit and 32bit instructions yields a better code density when compared to 8bit and 16bit architectures. This has significant advantages in terms of reduced memory requirements and maximizing the usage of precious on-chip Flash memory.
Binary upward compatible with all other Cortex-M processors
The Cortex-M0 has mainly 16bit Thumb-2 instructions and few 32bit ones. These instructions are also present on all the other Cortex-M processors. Hence all code written for the Cortex-M0 will run as is on the other processors.
Built-in low-power features
Sleep, deep sleep and state retention are three low power modes available to the user.
Optional Debug Access Port and Serial Wire Debug
For devices where every pin counts the serial wire debug port uses only two pins.
