The LM3S310-IGZ25-C2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris series, running at 25 MHz with 16 KB of Flash and 4K x 8 of SRAM.
At 25 MHz, the Cortex-M3 executes single-cycle multiply and hardware divide. The 4 KB SRAM limits lookup table size and stack depth.
The core runs at 25 MHz, which is the maximum clock from the internal oscillator or an external source.
