What is Cortex M0


The ARM Cortex™-M0 processor is the smallest, lowest power and most energy-efficient ARM processor available. 
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 it to be deployed in analog and mixed signal devices.




The Cortex-M family is an ideal solution for ranges of compatible, easy to use embedded devices such as microcontrollers (MCU) where different cost, power and performance considerations must be made. Each processor delivers an optimal trade-off for a broad embedded application range.

Cortex-M family processors are all binary upwards compatible, enabling software reuse and a seamless progression from one Cortex-M processor to another.
