Texas Instruments lists this part as obsolete. On-chip peripherals include brown-out detect/reset, POR, PWM, and a watchdog timer — enough for a standalone controller with minimal external supervision. The connectivity block covers I²C, IrDA, Microwire, SPI, SSI, and UART/USART, so the part can bridge to serial sensors, displays, and legacy peripherals without a separate interface IC. The 56 general-purpose I/O lines, combined with the internal oscillator, mean many designs can run without an external crystal or clock chip, saving board space and BOM cost. ## Package, temperature grade, and supply range The A/D converter is a 4-channel 10-bit type — suitable for slow analog inputs like temperature or potentiometer feedback, but not for high-speed data acquisition.","metaTitle":"Texas Instruments LM3S1636-IQC50-A2T MCU, 50MHz, 128KB Flash","metaDescription":"Texas Instruments LM3S1636-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 32KB RAM, 100-LQFP.
