The LM3S300-IQN25-C2: That memory footprint is sized for a single control loop plus a modest protocol stack — think a UART-to-SPI bridge, a PWM-driven fan controller, or a sensor hub that logs a few bytes of telemetry. The 36 general-purpose I/O and the internal oscillator keep the BOM lean for a 48-LQFP board.
The supplier device package is 48-LQFP (7x7).
It remains available for existing production runs but is not intended for new design starts. For new designs, evaluate a current-production Stellaris or Tiva-C alternative.
