Frequently asked questions
Is there a drop-in replacement with the same 48-LQFP footprint and 34 I/O?
No official cross-reference or second-source order code is documented for this part. 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.
Can I run this at 75°C ambient in an industrial panel?
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.
