The Texas Instruments LM3S1N11-IQC50-C0 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris 1000 series, clocked at 50 MHz with 64 KB of Flash program memory and 12K x 8 bytes of SRAM. It packs 67 general-purpose I/O lines, a 10-bit 8-channel ADC, and a full set of serial interfaces including I²C, SPI, UART, and LIN — making it a fit for industrial control panels, motor drives, and building-automation gateways that need a single-chip control core with moderate memory and peripheral count.
