A layout-compatible peer would need to match the 48-LQFP package, 34-I/O count, and 50MHz Cortex-M3 core with ≥64KB flash — but firmware HAL porting from the Stellaris register set will be required, and the Stellaris family does not share peripheral maps with the Tiva C Series that succeeded it."},{"question":"Can I run this at 75°C ambient in an industrial panel?","answer":"Yes — the rated operating temperature is -40°C to 85°C, so 75°C ambient leaves 10°C of margin at 3.3V nominal. Specific VCC derating curves for DMA-heavy firmware are not in the spec ledger; consult the full TI datasheet for the LM3S815."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3S815-IQN50-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/LM3S815-IQN50-C2T when reusing this data.
