Frequently asked questions
Does a pin-compatible alternative exist for rework or a second source?
The LM3S808-IQN50-C2T is the same 48-LQFP footprint with doubled SRAM (16KB vs 8KB); the I²C/SPI/UART pinout is unchanged, so it drops into the existing layout without a PCB respin. There is no officially validated second-source MCU from another manufacturer with the same pinout and Stellaris feature set.
What does the -40°C–85°C temperature grade cover for field deployment?
The -40°C–85°C ambient rating covers industrial enclosures and outdoor cabinets down to -20°C ambient — the cold-start POR is guaranteed at -40°C, so a warm-up delay is not required for cold ambient. However, this part is not AEC-Q100 qualified; it does not meet automotive qualification requirements without a separate qualification program.
How do I source this part for a panel-build RFQ?
Open an RFQ — the part is quoted-to-order through the broker channel due to the NRND/eol_hot status, and standard franchise stock positions on this specific order code are expected to be limited or depleted. Specify the 48-LQFP TR package and your quantity; the channel will confirm reel count and lead time against available positions.
