On-chip peripherals include PWM, DMA, I²S, and a quadrature encoder interface (QEI) for motor position feedback. Connectivity covers I²C, SPI, SSI, UART/USART, IrDA, and Microwire — enough serial interfaces to link multiple field devices or a host controller without external bridge chips. Texas Instruments lists the LM3S1P51-IQC80-C3 as obsolete.","metaTitle":"TI LM3S1P51-IQC80-C3 ARM Cortex-M3 MCU, 80MHz, 64KB Flash","metaDescription":"Texas Instruments LM3S1P51-IQC80-C3 Stellaris ARM Cortex-M3 MCU, 80MHz, 64KB Flash, 24KB RAM, 100-LQFP.
