The 64 KB Flash (64K x 8) holds moderate firmware images; the 24 KB SRAM (24K x 8) supports buffered UART or I²C data without external RAM. ## Peripherals and connectivity for industrial control ## 100-LQFP footprint and temperature grade Housed in a 100-LQFP (14x14 mm) surface-mount package, the MCU offers 67 GPIO lines for board-level interfacing. Mounting is standard surface-mount reflow; no exposed thermal pad, so heat dissipation relies on the package body and board copper.","metaTitle":"Texas Instruments LM3S1P51-IQC80-C5 ARM Cortex-M3 MCU","metaDescription":"Texas Instruments Stellaris LM3S1P51-IQC80-C5 ARM Cortex-M3 MCU at 80 MHz, 64 KB Flash, 24 KB RAM, 100-LQFP.
