The 50 MHz ARM Cortex-M3 core runs a lightweight TCP/IP stack alongside real-time control loops. This consolidates the BOM into a single chip, saving board space and reducing interconnect complexity. The 108-ball BGA (10x10 mm body) requires a multi-layer PCB with controlled-impedance traces for the Ethernet PHY interface — plan for four or more layers and a clean ground plane under the BGA footprint. This part is officially obsolete — no longer in production from Texas Instruments. There is no listed direct replacement from the manufacturer. For existing BOM lines, procurement must source through the independent surplus and broker channel. Store the reels dry — the BGA package is moisture-sensitive, and long-term storage without a dry cabinet risks solder-joint reliability.","metaTitle":"LM3S6633-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S6633-IBZ50-A2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32 KB RAM, Ethernet/I2C/SPI, -40°C to 85°C, 108-BGA.
