At this clock rate, a single-cycle multiply and hardware divide keep interrupt latency predictable — useful for PWM generation and motor commutation. The 48 KB SRAM is tight for heavy graphics buffers, but pairs well with the external bus interface (EBI/EMI) for off-chip memory expansion if needed. That means it can talk to serial sensors, CAN transceivers, external SRAM/Flash, and parallel LCDs without glue logic. The eight 12-bit ADC channels handle analog feedback from current sensors or potentiometers.","metaTitle":"LM3S1H11-IQC80-A2 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S1H11-IQC80-A2 Stellaris ARM Cortex-M3S 1000 MCU. 80 MHz, 512 KB Flash, 48 KB RAM, 67 I/O, 100-LQFP.
