Frequently asked questions
What is the replacement for LM3S612-EQN50-C2?
No official successor part number is listed in the lifecycle record. For a pin-compatible drop-in, check the Stellaris 600-series siblings such as the LM3S611 or LM3S613 — verify the Flash/RAM and peripheral set match your firmware image before requalifying.
What is the pinout of LM3S612-EQN50-C2?
The pinout follows the standard 48-LQFP Stellaris 600-series assignment. The datasheet (TI literature number SPMS001 or later revision) provides the full pin diagram and function table.
