Stellaris® ARM® Cortex™-M microcontrollers offer embedded MCU designers the option of obtaining 32-bit performance for the same price as their current 8- and 16- bit microcontroller designs. Designers who migrate to Stellaris benefit from great tools, small code footprint, and outstanding performance.

In addition, microcontroller applications built on the Stellaris family have access to the ARM ecosystem of silicon, development tools, support, and software, and a breadth of instruction-set compatible performance options that exist only in the ARM architectural community.

The Stellaris family offers the industry's first and broadest implementation of Cortex-M and the Thumb-2 instruction set. This technology combines both 16-bit and 32-bit instructions to deliver the optimal balance of code density and performance. Thumb-2 uses 26% less memory than pure 32-bit code to reduce overall system cost while delivering improved, better performance.
