On-chip block RAM totals 3833856 bits — roughly 3.8 Mbit — which buffers packet data, holds small look-up tables, or serves as line-rate FIFO memory without reaching for external SRAM. ## I/O count and package — what fits on the board 205 user I/O are brought out to a 381-ball CABGA (17x17 mm) — the 381-FBGA footprint is a common mid-density BGA that routes on a 4- to 6-layer PCB without exotic via-in-pad. ## Temperature grade and deployment environment It suits telecom line cards, test equipment, and industrial controllers that live in a conditioned or ventilated enclosure, but not extended outdoor or under-hood use. Production status is Active per Lattice's lifecycle record — no NRND or EOL notice on file. ## How it compares to the LFE5UM-45F-8BG381C Because both parts share the same 17x17 mm BGA footprint and supply voltage range, a board laid out for the 45F can accept the 85F as a drop-in upgrade — the extra I/O (205 vs 203) fits the same ball map, and the higher logic density is available without a PCB spin.","metaTitle":"LFE5UM-85F-7BG381C FPGA, 84000 LEs, 205 I/O, Active","metaDescription":"Lattice ECP5 FPGA, 84000 logic elements, 205 I/O, 3.8 Mbit block RAM, 381-CABGA.
