The 108-ball BGA (10x10 mm) keeps the footprint compact, but the fine-pitch array demands controlled reflow and X-ray inspection; this is not a hand-solderable part. ## Package and integration note 108-ball BGA, 10x10 mm body. 38 I/O. Internal oscillator. Supply voltage 2.25 V to 2.75 V.","metaTitle":"LM3S6618-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash","metaDescription":"LM3S6618-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32K x 8 RAM, Ethernet, 108-BGA, -40°C to 85°C.
