On-chip block RAM totals 589824 bits, enough for moderate FIFO, line buffer, or coefficient storage without external memory for many designs. The 256-CABGA (14x14 mm) package with 197 I/O demands a 4-layer or more PCB for fan-out of the 0.8 mm pitch BGA balls, typical for this density class. ## Industrial temperature range and supply rails Core supply is 1.045 V to 1.155 V — a tight 110 mV window that requires a regulated rail, not a raw board voltage. The 197 I/O banks can be configured with separate VCCIO rails, but the core rail must stay within this band for reliable operation. Surface-mount 256-LFBGA with a 14x14 mm body and 0.8 mm ball pitch — the same footprint as the 381-ball sibling, so a board laid out for the larger package can also accept this 256-ball variant if the extra I/O are not needed.","metaTitle":"LFE5U-12F-7BG256I Lattice ECP5 FPGA, 12000 LEs, 197 I/O","metaDescription":"Lattice Semiconductor LFE5U-12F-7BG256I ECP5 FPGA, 12000 logic cells, 197 I/O, 589 Kbit RAM, 256-CABGA.
