With 118 user I/O and a 1.045 V to 1.155 V core supply, this FPGA targets designs that need mid-range logic density in a compact BGA — think camera ISP pipelines, motor-control co-processors, or PCIe Gen 2 bridging where board real estate is the constraint. ## Industrial temperature range and supply rail tolerance The core supply tolerance of 1.045 V to 1.155 V means a standard 1.1 V rail with ±5 % regulation stays inside the window — no need for a precision LDO on this rail. The supplier device package is listed as 285-CSFBGA (10x10); the alternate package / case designation 285-LFBGA, CSPBGA confirms the same ball-out and substrate size.","metaTitle":"Lattice LFE5UM-85F-8MG285I ECP5 FPGA, 84K LEs, 118 I/O","metaDescription":"Lattice Semiconductor LFE5UM-85F-8MG285I ECP5 FPGA, 84000 logic cells, 3833856 bits RAM, 118 I/O, -40 to 100°C.
