The Texas Instruments LM3S301-IGZ20-C2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 300 series, running at 20 MHz with 16 KB of Flash and 2 KB of RAM.
At 20 MHz the Cortex-M3 delivers roughly 20 MIPS of deterministic throughput. The 16 KB Flash and 2 KB RAM limit firmware to a modest control stack.
