Typical applications include motor-control nodes, sensor bridges, and serial-communication modules where a small-footprint Cortex-M3 core is sufficient. The 25 MHz Cortex-M3 executes single-cycle multiply and hardware divide. The 6-channel 10-bit ADC is adequate for most sensor interfaces. ## 16 KB Flash / 4 KB RAM — firmware budget The 16 KB Flash and 4 KB RAM support a control firmware image and a UART buffer. Texas Instruments has marked the LM3S317-EQN25-C2T as obsolete. No factory last-time-buy window remains open. The 48-LQFP package measures 7 mm × 7 mm. It is a surface-mount part with 30 I/O lines.","metaTitle":"Texas Instruments LM3S317-EQN25-C2T MCU, 25MHz, 48-LQFP","metaDescription":"Texas Instruments LM3S317-EQN25-C2T Stellaris ARM Cortex-M3 MCU, 32-bit, 25MHz, 16KB Flash, 4Kx8 RAM, 30 I/O, -40°C to 105°C.
