The 6-channel 10-bit ADC handles sensor feedback without an external converter. ## Obsolete — sourcing reality for this part Texas Instruments has marked the LM3S317 as obsolete. No factory orders or last-time-buy window remain. For a repair bench, the practical move is to source a known-good pull or NOS tray from independent distribution. ## Peripherals and connectivity at a glance","metaTitle":"LM3S317-IQN25-C2 Stellaris ARM Cortex-M3 MCU, 25 MHz, 16 KB Flash","metaDescription":"LM3S317-IQN25-C2 Stellaris ARM Cortex-M3 MCU. 25 MHz core, 16 KB Flash, 4 KB RAM, 6x10-bit ADC, -40°C to 85°C.
