It carries 128 KB of Flash program memory and 32 KB of SRAM, with a peripheral set that includes I²C, SPI, SSI, UART, IrDA, and Microwire connectivity, plus four 10-bit ADC channels, PWM, and a watchdog timer. The 100-LQFP package provides 56 general-purpose I/O lines. Rated for -40°C to 85°C, it is suited for industrial control panels, motor drives, and sensor interface boards where a mid-range Cortex-M3 core handles protocol bridging and real-time loops. At 50 MHz, the Cortex-M3 single-cycle multiply and hardware divide keep interrupt latency tight enough for a 10 kHz current-loop or a Modbus RTU master polling six slaves. The 32 KB SRAM leaves room for a double-buffered UART FIFO and a modest protocol stack without external memory. Operates from 2.25 V to 2.75 V.","metaTitle":"LM3S1635-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S1635-IQC50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB SRAM, industrial temp -40°C to 85°C, NRND.
