On-chip peripherals include a brown-out detect/reset, DMA controller, I²S audio interface, POR, PWM outputs, and a watchdog timer. The 16-channel 10-bit ADC samples analog inputs without an external converter. ## Package, temperature, and board integration Rated for -40 to +85°C industrial temperature operation, it suits factory-floor controllers, outdoor telemetry gateways, and under-hood automotive modules (where the rest of the BOM also meets that grade). Texas Instruments lists this part as Obsolete.","metaTitle":"Texas Instruments LM3S5651-IQC80-C0T MCU, 80MHz, 128KB Flash","metaDescription":"Texas Instruments LM3S5651-IQC80-C0T Stellaris ARM Cortex-M3 MCU, 80MHz, 128KB flash, 32KB RAM, 100-LQFP, -40 to 85°C.
