The 24 KB RAM handles a moderate packet buffer. The peripheral list covers CAN, USB, multiple UARTs with IrDA and LIN support, SPI, I²C, and a quadrature encoder interface. The 16-channel 10-bit ADC is adequate for basic analog monitoring. ## Obsolete — sourcing reality for the LM3S5P31-IQC80-C1 This part is officially obsolete per the manufacturer. No last-time-buy window remains. That means the only channel is the independent surplus and broker market — which is exactly where we source it. We can. ## Replacement and cross-reference No official direct replacement from TI is listed for this part. The revision variant shares the same base number but may carry errata differences.","metaTitle":"LM3S5P31-IQC80-C1 Stellaris ARM Cortex-M3 MCU, 80 MHz, 64 KB Flash, Obsolete","metaDescription":"LM3S5P31-IQC80-C1 is a 32-bit ARM Cortex-M3 MCU from the Stellaris 5000 series, 80 MHz, 64 KB Flash, 24 KB RAM, industrial temp.
