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.","metaTitle":"LM3S8970-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 100-LQFP","metaDescription":"LM3S8970-IQC50-A2 32-bit ARM Cortex-M3 MCU from TI Stellaris series. 50 MHz, 256 KB Flash, 64 KB RAM, Ethernet + CAN, -40 to 85°C.
