The 25 MHz Cortex-M3 core delivers adequate throughput for UART polling, sensor readout, and PWM generation at moderate update rates. It will not sustain real-time audio processing or high-speed data logging — the 4 KB RAM and 16 KB Flash are the actual constraints. For a control loop with a few hundred lines of C and a handful of state variables, this part fits without over-spending on a larger Stellaris sibling. The 36 I/O lines are on the perimeter leads.","metaTitle":"LM3S300-EQN25-C2T Stellaris ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash","metaDescription":"Obsolete LM3S300-EQN25-C2T 32-bit MCU from TI's Stellaris series. 25 MHz Cortex-M3, 16 KB Flash, 4 KB RAM, 48-LQFP, -40 to 105°C.
