The part is surface-mount in a 100-LQFP package (14x14 mm) with 46 available I/O, and operates from 2.25 V to 2.75 V over the industrial temperature range of -40 to 85 °C. That temperature grade suits it for factory-floor enclosures, outdoor telecom cabinets, and engine-bay electronics where ambient heat cycles are a given.
The LM3S8970-IQC50-A2 is marked as end-of-life (hot). TI has moved the Stellaris line to its legacy portfolio; no further production runs are planned. For new BOM lines or a last-time-buy, we source sealed reels from factory excess and auction lots — date-code spread and original packaging condition are confirmed at quote.
