Core supply is 1.045 V to 1.155 V — a 1.1 V rail with ±5 % regulation covers it. ## Temperature grade and environment The part lives in an enclosure that sees ambient up to 85°C with a 15°C junction rise; above that the airflow or heatsink must keep Tj under 100°C or the timing model shifts. The 256-CABGA package is a 14x14 mm body, 1.0 mm max height, with a 0.80 mm ball pitch. The centre ground pad is not an exposed paddle — thermal relief goes through the solder balls to the PCB plane. A 2-second 260°C peak reflow profile per J-STD-020 works; moisture sensitivity level is MSL 3 (168-hour floor life) typical for this package family. ## Speed grade and peer comparison The -8 speed grade is the fastest standard option in the LFE5U-25 family — the sibling LFE5U-25F-6BG256I is a -6 grade, roughly 25 % slower on the worst-case timing paths (the exact delta depends on the design's critical path). If the board was laid out for the -6, the -8 drops in without any PCB change; the only difference is the speed bin, so the BOM line swaps directly. Stepping up to the LFE5U-45F-7BG256I doubles the logic to 44,000 cells and the block RAM to 2 Mbit, but the package stays 256-CABGA — same footprint, same ball-out. That is a real drop-in upgrade path if the design outgrows the 25K fabric, though the -7 speed grade is one notch below the -8. The part ships in a tray, not tape-and-reel, so plan for pick-and-place with a tray feeder or a tube-to-tape conversion.","metaTitle":"Lattice LFE5U-25F-8BG256I ECP5 FPGA, 24K LEs, 197 I/O","metaDescription":"LFE5U-25F-8BG256I ECP5 FPGA from Lattice: 24K logic cells, 197 I/O, 1 Mbit block RAM, -40 to 100°C.
