LFE5U-85F-6BG554C

The LFE5U-85F-6BG554C is a commercial‑grade member of the ECP5 FPGA family from Lattice Semiconductor Corporation. It provides a mid‑density programmable fabric with 84,000 logic elements, approximately 3.83 Mbits of embedded RAM, and 259 user I/O pins in a 554‑ball FBGA package.

Designed for applications that require flexible I/O, on‑chip memory, and integrated FPGA architecture features referenced in the ECP5 family data sheet (clocking, programmable I/O, DDR support, SERDES/PCS and device configuration), this device targets a range of embedded and communications designs where integration and predictable operating conditions matter.

Key Features

• Logic Capacity — 84,000 logic elements (cells) to implement combinational and sequential logic for mid‑range FPGA designs.
• Embedded Memory — Approximately 3.83 Mbits of on‑chip RAM to support buffering, FIFOs, and local data storage.
• I/O Resources — 259 user I/O pins to accommodate wide buses, multiple interfaces, and complex board‑level connectivity.
• Programmable Fabric & Architecture — Based on the ECP5 family architecture with documented features including slices, routing, clocking structures (sysCLOCK PLL and distributed clock network), programmable I/O cells, DDR memory support, and SERDES/PCS blocks.
• Package & Mounting — 554‑FBGA (supplier package: 554‑CABGA, 23 × 23 mm) in a surface‑mount form factor for compact PCB layouts.
• Power & Operating Range — Core supply range specified from 1.045 V to 1.155 V; designed to operate in commercial temperature range from 0 °C to 85 °C.
• Manufacturing & Environmental — RoHS compliant and supplied by Lattice Semiconductor Corporation as a commercial‑grade device.

Typical Applications

• Communications & Protocol Bridging — High I/O count and documented SERDES/PCS and programmable I/O support make this device suitable for implementing protocol conversion, interface bridging, and packet processing logic.
• Embedded Systems — On‑chip memory and flexible logic resources enable local buffering, custom peripheral integration, and control functions in embedded controllers and appliances.
• Video & Imaging Front‑Ends — The combination of abundant I/O and embedded RAM supports frame buffering, data alignment, and pre‑processing tasks in video capture and distribution modules.
• Industrial Automation — Deterministic programmable logic and wide I/O availability support motor control interfaces, sensor aggregation, and machine control functions within the commercial temperature range.

Unique Advantages

• Balanced Integration: Combines a sizable logic capacity (84,000 logic elements) with multi‑Mbit on‑chip memory for designs that need both compute and storage on a single device.
• High I/O Density: 259 user I/O pins simplify board routing for wide buses and multiple external interfaces, reducing the need for external glue logic.
• Family Feature Set: Leverages documented ECP5 family features—clocking infrastructure, programmable I/O, DDR support, and SERDES/PCS blocks—so designers can use established architecture capabilities from the datasheet.
• Compact Package: 554‑FBGA (23 × 23 mm) surface‑mount package enables compact PCB implementations while preserving connectivity and thermal footprint.
• Commercial Availability: Commercial grade device with RoHS compliance suitable for a wide range of mainstream electronic products operating between 0 °C and 85 °C.
