The 128 KB on-chip Flash and 32K x 8 SRAM provide enough headroom for a modest RTOS plus application stack, with the SRAM handling time-critical interrupt vectors. Connectivity covers I²C, SPI, SSI, UART/USART, IrDA, Microwire, and QEI — enough serial interfaces for sensor fusion or motor-feedback loops without external bridge chips. The 33 GPIOs and 4-channel 10-bit ADC serve mixed-signal control applications. Supply voltage is 2.25 V to 2.75 V — a single 2.5 V rail powers the core and I/O, simplifying the power tree. ## 64-LQFP — board integration notes Housed in a 64-LQFP with a 10x10 mm body (EIAJ standard), the package has a 0.5 mm pitch that typically requires a 4-layer PCB for clean fan-out of the peripheral signals. The exposed pad on the underside provides a low-thermal-resistance path to the ground plane — ensure the pad is soldered to the board copper for rated junction-to-ambient performance.","metaTitle":"LM3S1627-IQR50-A0 Texas Instruments ARM Cortex-M3 MCU, 50MHz","metaDescription":"Texas Instruments LM3S1627-IQR50-A0 Stellaris ARM Cortex-M3 MCU, 50MHz, 128KB Flash, 32K RAM, NRND.
