If your board already runs a 3.3 V rail, you will need a dedicated LDO or a buck converter to drop to 2.5 V nominal. ## 108-BGA (10x10 mm) — rework and inspection The LM3S2608-IBZ50-A2T comes in a 108-ball LFBGA, 10x10 mm body. That is a fine-pitch BGA — expect to need X-ray inspection for voiding and alignment after reflow. The 0.8 mm ball pitch is manageable with a standard rework station, but the 10x10 mm footprint means the part sits in the middle of the board, not at the edge, so bottom-side preheat is needed for hand rework.","metaTitle":"LM3S2608-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S2608-IBZ50-A2T ARM Cortex-M3 MCU, 50 MHz, 128 KB Flash, 32K x 8 RAM, -40 to 85°C, 108-BGA.
