The part is housed in a 48-LQFP package (7x7 mm) and rated for the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, motor control, and embedded control panels where a moderate-performance Cortex-M3 core is sufficient. At 50 MHz, this Cortex-M3 executes single-cycle multiply and hardware divide, enough for PID loops running at a few kHz. The 8 KB RAM is the tighter resource: a full TCP/IP stack won't fit, but a lightweight serial protocol handler will. ## Obsolete — sourcing reality for the BOM line The LM3S611-IQN50-C2T is officially obsolete (EOL). No last-time-buy window remains open from the manufacturer.","metaTitle":"LM3S611-IQN50-C2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 32 KB Flash","metaDescription":"Obsolete LM3S611-IQN50-C2T 32-bit ARM Cortex-M3 MCU from TI Stellaris series. 50 MHz, 32 KB Flash, 8 KB RAM, 48-LQFP, -40°C to 85°C.
