It packs 67 GPIOs, a 10-bit 8-channel ADC, and a suite of serial interfaces — I²C, SPI, SSI, UART, LIN, IrDA, and Microwire — making it suited for industrial control panels, sensor hubs, and motor-drive front ends that need moderate processing and broad peripheral connectivity. The -40°C to 85°C industrial temperature grade covers factory-floor and outdoor telecom cabinets without derating concerns. ## 50 MHz core — what it means for control loops and protocol handling The Cortex-M3 at 50 MHz handles PID loops and Modbus RTU framing. The DMA controller offloads UART or SPI data transfers. ## Memory and connectivity — what the 64 KB Flash and 12 KB RAM support 64 KB of Flash supports a bootloader, a real-time kernel, and application code for a single-protocol device. 12 KB SRAM leaves room for UART buffers and a data array.","metaTitle":"TI LM3S1N11-IQC50-C5T ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"Texas Instruments LM3S1N11-IQC50-C5T 32-bit ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 12 KB RAM, 67 I/O, -40°C to 85°C, 100-LQFP.
