No specific pin-compatible drop-in successor order code is cited on this part's ledger — validate the target TM4C device's pinout, peripheral mapping, and voltage rails against the existing board before committing a replacement run."},{"question":"Can I socket the 100-LQFP for field replacement?","answer":"Standard 100-LQFP socket adapters exist, but they add profile height and contact resistance. For a one-off repair, hot-air rework of the LQFP directly onto the existing pad pattern is feasible if the board was designed with rework clearance around the package. A new Gerber for a direct-solder replacement requires confirmation of the 0.5 mm pitch pad geometry."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S9L97-IQC80-C1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S9L97-IQC80-C1 when reusing this data.
