The 60 general-purpose I/O lines, combined with the serial interface set (I²C, SPI, SSI, UART/USART, IrDA, Microwire), make this a candidate for industrial sensor hubs or motor-control panels where multiple fieldbuses share a single controller. ## Package, temperature, and supply rails Housed in a 100-pin LQFP (14x14 mm), the part demands a 4-layer PCB for clean fan-out — the 0.5 mm pitch limits escape routing on two-layer boards.","metaTitle":"TI LM3S1911-IQC50-A2 ARM Cortex-M3 MCU, 50MHz, 256KB Flash","metaDescription":"Texas Instruments LM3S1911-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 256KB Flash, 64KB RAM, -40 to 85°C, 100-LQFP.
