LFE5U-85F-7BG554C

Product Overview

The LFE5U-85F-7BG554C is an ECP5 field programmable gate array from Lattice Semiconductor Corporation. It provides programmable logic, on-chip RAM, and 259 I/O in a surface-mount 554-CABGA (23x23) package. The device operates from a 1.045V to 1.155V supply and is specified for a junction temperature range of 0°C to 85°C, for embedded logic, interface adaptation, and data buffering designs.

Key Features

• 84000 logic elements/cells and 21000 LABs/CLBs provide programmable logic capacity for embedded digital designs.
• 3,833,856 total RAM bits support on-chip data buffering and temporary storage.
• 259 I/O channels provide external digital device connectivity.
• 1.045V to 1.155V supply range defines the operating supply limits.
• 0°C to 85°C (TJ) operating range guides thermal design for junction temperature control.
• 554-CABGA (23x23) surface-mount package and 554-FBGA case define the PCB footprint.

Applications

• Embedded control logic and state machines in programmable hardware designs.
• Interface bridging between digital peripherals and programmable logic using available I/O resources.
• On-chip data buffering and temporary storage supported by the available RAM bits.
• Programmable signal routing and glue logic for board-level integration.

Design & Procurement Notes

Designers should confirm that the required logic capacity, I/O count, and RAM bits fit the 84000 logic elements/cells, 259 I/O, and 3,833,856 total RAM bits available in this ECP5 device. The 1.045V to 1.155V supply range requires regulated power delivery within those limits, and the 0°C to 85°C (TJ) rating should be evaluated using junction temperature rather than ambient temperature alone. PCB layout should match the 554-CABGA (23x23) surface-mount footprint and 554-FBGA package, with attention to thermal dissipation and signal integrity for the 259 I/O channels.
