For a control loop or protocol stack that fits in 16 KB of on-chip flash, the Cortex-M3 delivers deterministic interrupt latency without a cache. ## On-chip memory and peripheral mix Program memory is 16 KB of FLASH (16K x 8), backed by 4K x 8 of SRAM. The 32 general-purpose I/O pins break out alongside a 4-channel 10-bit ADC, a PWM generator, and a watchdog timer. Serial connectivity covers I²C, SPI, SSI, Microwire, and UART/USART — enough to bridge to sensors, displays, or a host processor. ## Package, supply, and temperature grade Housed in a 48-VFQFN Exposed Pad (7x7 mm), the LM3S316-IGZ25-C2 requires a surface-mount reflow profile with the exposed paddle soldered to a thermal land on the PCB — this is the primary heat path. No last-time-buy or end-of-life notice applies.","metaTitle":"LM3S316-IGZ25-C2 TI Stellaris ARM Cortex-M3 MCU, 25MHz","metaDescription":"LM3S316-IGZ25-C2 Texas Instruments Stellaris ARM Cortex-M3S 300 MCU, 25MHz, 16KB Flash, 4KB RAM, -40 to 85°C, 48-QFN.
