The commercial temperature grade (0°C to 85°C junction) fits indoor equipment, telecom shelters, and industrial control cabinets — not rated for the -40°C automotive or outdoor extremes that the industrial-temp sibling (LCMXO3LF-4300C-5BG256I) covers. ## Package and board-fit considerations The 400-CABGA (17x17 mm) with 0.80 mm ball pitch is a four-layer PCB minimum for fan-out — the 335 I/O demand a via-in-pad or microvia strategy if the inner rows are used; the 256-ball variant (LCMXO3LF-4300C-5BG256I) drops to 206 I/O but relaxes the board layer count.","metaTitle":"LCMXO3LF-4300C-5BG400C Lattice MachXO3 FPGA, 4320 LEs","metaDescription":"Lattice LCMXO3LF-4300C-5BG400C MachXO3 FPGA, 4320 logic cells, 335 I/O, 94 Kbit RAM, 400-CABGA.
