Product details

84K logic cells in a 10x10 mm BGA — the density-per-mm² play

The LFE5UM-85F-8MG285I is the highest-density member of Lattice's ECP5 family in the 285-ball CSPBGA footprint, packing 84000 logic elements and 3833856 bits of block RAM into a 10x10 mm package. 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.

Frequently asked questions

What is the closest functional second-source to LFE5UM-85F-8MG285I?

The LFE5UM-45F-7BG381I is the next step down in the same ECP5 family, with 44000 logic cells and 1990656 RAM bits in a 381-ball BGA — but it has 203 I/O and a different package footprint (17x17 mm), so it is not a pin-drop replacement. A board layout change is required to migrate down.

What compliance documentation does Lattice provide for LFE5UM-85F-8MG285I?

The part is supplied in a RoHS-compliant tray package. Lattice publishes the full datasheet, IBIS models, and PCN archive for the ECP5 family through their documentation portal. Specific REACH and conflict-minerals declarations are available on request.
