The part is built for industrial control, building automation, and networked sensor nodes that need a single-chip Ethernet gateway — the integrated MAC/PHY saves an external transceiver on the BOM. Operating from 2.25 V to 2.75 V over -40°C to 85°C, it fits factory-floor and outdoor telecom enclosures where extended temperature is mandatory. The 50 MHz Cortex-M3 core runs a lightweight TCP/IP stack and handles Modbus TCP or Ethernet/IP polling without a separate communications processor.","metaTitle":"LM3S6633-IBZ50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S6633-IBZ50-A2 is an obsolete Stellaris ARM Cortex-M3 MCU with 50 MHz core, 128 KB Flash, 32 KB RAM, Ethernet, industrial temp.
