Connectivity includes I²C, SPI, SSI, UART/USART, and Microwire — enough serial interfaces for a sensor hub or motor-control node without external bridge chips. On-chip peripherals include a PWM, watchdog timer, and brown-out detect/reset — the PWM can drive a small BLDC motor directly through a gate driver. No second-source cross-reference exists — a board spin is required for any functional replacement.","metaTitle":"LM3S801-IQN50-C2 TI Stellaris Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S801-IQN50-C2 Stellaris ARM Cortex-M3 MCU, 50MHz, 64KB Flash, 8KB RAM, 48-LQFP.
