Connectivity includes CANbus, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, and USB — covering fieldbus, sensor, and human-interface links from a single chip. The 67 GPIOs provide enough pins to interface with external memory, displays, and discrete sensors without a port expander. On-chip peripherals include a brown-out detect/reset, DMA controller, POR, PWM outputs, and a watchdog timer. The 16-channel 10-bit ADC captures analog signals from multiple sensors or potentiometers without an external multiplexer. Texas Instruments lists the LM3S5P31-IQC80-C0T as obsolete. No official successor or pin-compatible replacement is recorded in the product documentation. Availability and current pricing are verified at quote time.","metaTitle":"LM3S5P31-IQC80-C0T Texas Instruments MCU, 80MHz Cortex-M3","metaDescription":"Texas Instruments LM3S5P31-IQC80-C0T Stellaris ARM Cortex-M3 MCU, 80MHz, 64KB flash, 24KB RAM, CAN/USB, 100-LQFP.
