With 1,990,656 bits of block RAM on die, this part handles moderate-depth FIFOs, line buffers for video pipelines, or small processor caches without gluing on external SRAM. ## Core supply and I/O — what the 1.1V rail demands of the board The core supply range is 1.045V to 1.155V — a 1.1V nominal rail that must stay within 5% including ripple and load transient. A switching regulator with 1% set-point accuracy and a low-ESR output cap is the usual choice; an LDO adds dropout headroom if the upstream rail is 1.2V. The 381-CABGA footprint at 0.8 mm pitch routes cleanly on a 4-layer board with microvias; a 6-layer stack-up gives room for a solid ground plane under the core and separate power islands for the I/O banks. 203 I/O means most of the 381 balls are signal pins — the remaining balls are core and I/O supply pairs. Decouple each VCCIO bank with a 1 µF ceramic per four pins and a 10 µF bulk per bank, placed within 5 mm of the balls. ## Active lifecycle and compliance — no end-of-life watch needed ROHS3 Compliant per Lattice's declaration, with no RoHS exemption expiry to track. The part ships in a standard Tray carrier for pick-and-place.","metaTitle":"Lattice LFE5UM-45F-7BG381I ECP5 FPGA, 44K LE, 203 I/O","metaDescription":"Lattice ECP5 FPGA LFE5UM-45F-7BG381I: 44,000 logic elements, 203 I/O, 1.9 Mbit block RAM, 381-CABGA, -40°C to 100°C.
