For new designs or long-production runs, begin Tiva C qualification now. For a repair board or a frozen BOM running existing firmware, the part remains accessible through distribution in the near term but allocation limits and lot-date constraints will tighten — plan your last-time-buy accordingly and do not wait for a PCN to force the decision."},{"question":"The data sheet shows -40°C to 105°C. Can I use this part at 105°C ambient with the core running at 50MHz full time?","answer":"The -40°C to 105°C ambient rating is the spec, but thermal headroom at the high end depends on your board layout and the VFQFN exposed-pad solder quality. At 105°C ambient with the 3.6V rail and full core load, junction margin is tighter than it looks on the ambient spec alone — confirm the pad is properly landed and that no adjacent components are heating the MCU zone."},{"question":"Is there a pin-compatible or drop-in replacement for the LM3S812-EGZ50-C2T?","answer":"TI's Stellaris-to-Tiva migration is the official successor path, but the Tiva variants in the same 48-pin count come in VFQFN and LQFP packages with different pinouts — they are not pin-for-pin drop-ins. A layout spin is required to move to a Tiva part number. Check the specific Tiva variant pinout against your board's signal map before committing a redesign."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S812-EGZ50-C2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3S812-EGZ50-C2T when reusing this data.
