LFE5UM-45F-8BG554I

The LFE5UM-45F-8BG554I is an industrial-grade ECP5 family FPGA from Lattice Semiconductor, offering 44,000 logic elements in a high-density 554-ball FBGA package. This device integrates a sizable I/O complement and embedded memory in a compact surface-mount package, supporting designs that require configurable logic, interface aggregation and deterministic operation across a wide temperature range.

Family-level documentation describes comprehensive on-chip resources such as programmable I/O, clocking, DSP and SERDES building blocks, making the device suitable for systems that need flexible I/O, memory and timing options within industrial operating conditions.

Key Features

• Core Capacity — 44,000 logic elements for mid-density programmable logic and glue-logic integration.
• Embedded Memory — Approximately 1.99 Mbits of on-chip RAM (1,990,656 bits) to support buffering, FIFOs and small on-chip data stores.
• I/O Resources — 245 user I/Os to implement wide parallel interfaces, multiple serial lanes, or mixed-signal I/O arrangements.
• Package & Mounting — 554-ball FBGA (supplier package: 554-CABGA, 23 × 23 mm) in a surface-mount format for compact board-level integration.
• Power — Core supply operating range 1.045 V to 1.155 V to match regulated low-voltage FPGA power rails.
• Industrial Temperature Range — Rated for −40 °C to 100 °C for use in industrial environments.
• Family-Level Architecture — ECP5 family data sheet documents programmable I/O cells, sysCLOCK PLLs, memory blocks, sysDSP slices, SERDES and DDR support for advanced interface and signal-processing use cases.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Controls — Industrial-grade temperature rating and flexible I/O make the device suitable for control logic, protocol bridging and I/O aggregation in automation equipment.
• Interface Bridging and Protocol Conversion — Large I/O count and documented SERDES/PIO resources support designs that translate between parallel and serial interfaces or consolidate multiple buses.
• Embedded Processing and Acceleration — On-chip memory and sysDSP slice capabilities (as described in the family data sheet) enable localized datapath acceleration and buffering for embedded applications.

Unique Advantages

• High Logic Density: 44,000 logic elements provide substantial programmable capacity for mid-range applications without moving to a larger form factor.
• Generous I/O Footprint: 245 I/Os allow implementation of broad peripheral sets, parallel interfaces or multiple independent channels on a single device.
• Integrated Memory: Approximately 1.99 Mbits of embedded RAM simplifies design by reducing external memory requirements for many buffering and control tasks.
• Industrial Robustness: −40 °C to 100 °C operating range and RoHS compliance align the device with industrial product requirements and regulatory expectations.
• Compact, Surface-Mount Package: 554-FBGA (23 × 23 mm supplier package) delivers high pin density in a footprint suitable for space-constrained PCBs.
• Family Documentation for System Design: The ECP5 family data sheet details clocking, I/O, memory, DSP and SERDES features to inform system-level integration and verification.
