Frequently asked questions
What replaces the LM3S812?
The Stellaris family transitioned broadly to the Tiva TM4C series, but this ledger carries no official cross-reference for the LM3S812 specifically. A pin-compatible drop-in is not confirmed in the record; any TM4C candidate would need layout verification against the 48-LQFP footprint and peripheral mapping.
Does the 2×10-bit ADC and the brown-out reset hold certifications on a legacy panel?
The EOL status does not automatically revoke existing certifications, but a customer audit requiring an updated doc pack should flag that the brown-out reset threshold is fixed by the IC — there is no adjustable trip point. Request the TI PCN package if a recertification trace is required.
