ARM Cortex-M Processors

ARM Cortex™ M Processors


The ARM Cortex™-M processor family is an upwards compatible range of energy-efficient, easy to use processors. The ARM Cortex-M3 and Cortex-M0 processors utilize the ARM Thumb®-2 technology which provides excellent code density, and supports a fundamental base of 16-bit Thumb instructions, extended to include more powerful 32-bit instructions. In many cases a C compiler will use the 16-bit version of the instruction unless the operation can be carried out more efficiently using a 32-bit version.
