The 381-CABGA (17x17 mm) footprint is a standard BGA array; the 0.8 mm ball pitch routes cleanly on a 4-layer board with via-in-pad if the thermal vias are planned. ## Peer fit — speed grade and temperature grade differences The -8 speed grade on this variant is the fastest in the LFE5U-12 family — the -6 grade peers (LFE5U-12F-6BG256I, LFE5U-12F-6BG381I) share the same 12000 LUT count, 197 I/O, and 589824-bit RAM, but the -8 delivers tighter timing margins for the same logic. The commercial-temperature peer LFE5U-12F-6BG256C (0°C to 85°C) is a cost-reduction option if the end system never sees the industrial range, but the -8BG381I's wider temperature envelope avoids a qualification respin later.","metaTitle":"Lattice LFE5U-12F-8BG381I ECP5 FPGA, 12K LUTs, 197 I/O","metaDescription":"LFE5U-12F-8BG381I ECP5 FPGA, 12000 LUTs, 197 I/O, 589824 bits RAM, -40°C to 100°C, 381-CABGA.

The ball count and footprint differ, so the PCB layout must be revised.
