LFE5UM-85F-8MG285C

The LFE5UM-85F-8MG285C is an ECP5-series Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor, supplied in a 285-ball LFBGA/CSPBGA package. It provides a balanced combination of programmable logic, embedded memory, and I/O resources for commercial-grade applications.

Built around the ECP5 family architecture, this device supports on-chip memory blocks, DSP-like slices, programmable I/O and clocking resources described in the ECP5 data sheet, making it suitable for designs that require flexible logic implementation, moderate embedded RAM, and a substantial I/O count.

Key Features

• Logic Capacity — 21,000 CLBs (configurable logic blocks) and 84,000 logic elements provide substantial programmable logic for custom digital functions.
• Embedded Memory — Approximately 3.83 Mbits of on-chip RAM (3,833,856 total RAM bits) for buffering, FIFOs and local data storage.
• I/O Resources — 118 user I/O pins with programmable I/O cell architecture as described in the ECP5 family data sheet.
• Clocking and Timing — Integrated clocking structures including sysCLOCK PLL and comprehensive clock distribution described in the ECP5 documentation.
• High-speed Interfaces and Memory Support — Device family features such as SERDES blocks, DDR memory support, and physical coding sublayer capabilities are included in the ECP5 data sheet.
• Package and Mounting — 285-LFBGA (285-CSFBGA, 10×10) surface-mount package for compact board-level integration.
• Power — Nominal supply operating range of 1.045 V to 1.155 V.
• Operating Conditions — Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Compliance — RoHS compliant.

Typical Applications

• Custom FPGA-based logic — Implement glue logic, protocol bridging or custom state machines using 84,000 logic elements and the ECP5 architecture.
• Memory-intensive designs — Use approximately 3.83 Mbits of embedded RAM and DDR memory support (per ECP5 data sheet) for buffering, packet queues or local storage.
• High-speed serial and interface functions — Leverage SERDES and programmable I/O cells for serial links and interface converters described in the ECP5 documentation.
• Embedded control and I/O aggregation — Consolidate multiple digital peripherals onto a single FPGA using 118 user I/Os and on-chip clocking resources.

Unique Advantages

• Substantial logic density — 84,000 logic elements and 21,000 CLBs enable complex designs without multiple discrete programmable devices.
• Integrated embedded RAM — Approximately 3.83 Mbits of on-chip memory reduces external memory requirements for many buffering and data-path tasks.
• Rich I/O and interface capability — 118 I/Os plus documented SERDES and DDR support in the ECP5 family enable diverse connectivity options.
• Compact surface-mount package — 285-LFBGA (10×10) package provides a high-density solution for space-constrained PCBs.
• Commercial temperature and RoHS compliance — Fits standard commercial applications and meets RoHS requirements for environmental compliance.
• ECP5 family architecture — Features such as programmable I/O cells, sysDSP slices, sysMEM blocks, PLLs and device configuration options are included in the ECP5 family documentation for integrated system design.
