At 50 MHz the ARM Cortex-M3 core delivers single-cycle multiply and hardware divide, which keeps interrupt latency tight for PID loops and encoder-edge counting. The 8 KB SRAM is sized for moderate data buffers — enough for a Modbus RTU frame or a few sensor logs — but not for large display frame stores or multi-protocol stacks. ## Peripheral set and ADC for mixed-signal control The 8-channel 10-bit ADC samples at rates adequate for current-sense and temperature-monitor inputs in motor-drive and power-supply feedback loops.","metaTitle":"Texas Instruments LM3S808-IQN50-C2 ARM Cortex-M3 MCU, 50 MHz","metaDescription":"TI Stellaris LM3S808 ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 8 KB RAM, 28 I/O, -40°C to 85°C, 48-LQFP.
