Expect date codes to be non-current, and plan for incoming inspection to verify authenticity and condition. ## Package and assembly notes for the 108-BGA The 108-LFBGA (10x10 mm body) uses a 0.8 mm ball pitch — standard for BGA rework stations but tight for hand assembly. Supply voltage is 1.08 V to 1.32 V core, which means a dedicated 1.2 V rail is needed alongside the 3.3 V I/O supply. Plan for a separate LDO or switching regulator for the core rail.","metaTitle":"LM3S5K31-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"LM3S5K31-IBZ80-C5 Stellaris ARM Cortex-M3S 5000 MCU, 80MHz, 128KB Flash, 24Kx8 RAM, 108-BGA.
