Core architecture and memory map
The LM3S1911-IQC50-A2T: The 60 general-purpose I/O pins, combined with I²C, SPI, UART, and IrDA connectivity, give it the flexibility to interface with multiple peripherals on a single board — displays, encoders, and serial sensors — while the internal oscillator reduces BOM count.
Temperature grade and supply rails
The 100-LQFP package (14x14 mm body) is a standard fine-pitch QFP that routes easily on a four-layer board; the exposed paddle is not present, so thermal management relies on the package's own junction-to-ambient path.
Texas Instruments lists this part as obsolete.
