That 50 MHz core on a single-cycle multiply architecture handles a 10 kHz current-control loop with margin for the comms stack. Connectivity covers Microwire, QEI (for quadrature encoder feedback), SPI, SSI, and UART/USART. The 30 I/O pins in the 48-LQFP leave room for a keypad, status LEDs, and a few discrete signals alongside the serial buses.","metaTitle":"Texas Instruments LM3S818-IQN50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"TI LM3S818-IQN50-C2 ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 8 KB RAM, 6x10b ADC, -40°C to 85°C, 48-LQFP.
