LFE5UM5G-85F-8BG381C

Product Overview

The LFE5UM5G-85F-8BG381C from Lattice Semiconductor Corporation is an ECP5-5G field programmable gate array intended for embedded programmable logic designs. It is supplied in a surface-mount 381-FBGA package, also identified as 381-CABGA (17x17). The device provides 205 I/O, 84,000 logic elements/cells, 21,000 LABs/CLBs, and 3,833,856 total RAM bits. Its specified supply voltage range is 1.045 V to 1.155 V, and its operating temperature range is 0°C to 85°C (TJ). This part is suited to board-level implementations where programmable digital logic, I/O control, and on-chip memory resources need to be integrated into a compact BGA footprint.

Design & Procurement Notes

Design teams should plan the core supply within the specified 1.045 V to 1.155 V range and provide stable decoupling for the 381-CABGA (17x17) BGA footprint. PCB layout, via fan-out, solder paste, reflow profile, and inspection should account for the surface-mount package and 205 I/O signal routing. Thermal design should keep junction temperature within 0°C to 85°C under expected operating conditions. Resource planning should consider the 84,000 logic elements/cells, 21,000 LABs/CLBs, and 3,833,856 total RAM bits when defining logic, buffering, and I/O partitioning.
