It runs at 25 MHz with 16 KB of Flash program memory and 4K x 8 of SRAM, giving it enough compute and storage for basic control, sensor interface, or serial-communication tasks in industrial or embedded systems. The 36 general-purpose I/O lines and built-in serial interfaces — Microwire, SPI, SSI, UART/USART — let it handle moderate I/O and protocol bridging without external logic. Supply range of 3V to 3.6V lets it run from a standard 3.3V rail without an extra regulator.","metaTitle":"LM3S310-IQN25-C2T Stellaris ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash, 48-LQFP","metaDescription":"LM3S310-IQN25-C2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 300 series, 25 MHz, 16 KB Flash, 4K x 8 RAM, 36 I/O, industrial temp -40°C to 85°C, 48-LQFP.
