LFE5U-45F-7BG554I

The LFE5U-45F-7BG554I is an industrial-grade FPGA from the Lattice ECP5 family. It provides a balanced combination of logic density, embedded memory and I/O capacity for mid-range programmable-logic applications.

This device features 44,000 logic elements across approximately 11,000 logic blocks, roughly 1.99 Mbits of on-chip RAM, and 245 user I/O — making it suitable for industrial systems that require extended temperature operation, a high I/O count, and compact surface-mount packaging.

Key Features

• Core Logic 44,000 logic elements organized across about 11,000 logic blocks to implement control, glue logic and custom datapaths.
• Embedded Memory Approximately 1.99 Mbits of on-chip RAM for frame buffers, FIFOs, state storage and local data buffering.
• I/O Capacity 245 user I/O pins provide extensive connectivity for external peripherals, sensors and parallel interfaces.
• Power and Supply Core supply range from 1.045 V to 1.155 V, allowing precise power budgeting and compatibility with matching regulator rails.
• Package and Mounting 554-ball FBGA package (supplier package: 554-CABGA, 23×23) in a surface-mount form factor for high-density PCB layouts.
• Temperature Range Industrial operating range from −40 °C to 100 °C for deployment in extended-temperature environments.
• Compliance RoHS-compliant construction to meet environmental and assembly requirements.
• Family-Level Architecture (ECP5) The ECP5 family data sheet describes architecture elements such as programmable I/O cells, PLLs/clocking, DDR memory support and SERDES/PCS blocks that characterize the series.

Typical Applications

• Industrial Control and Automation — Leverage the device’s industrial temperature rating, large I/O count and programmable logic for motor drives, PLC interfaces and machine control logic.
• Protocol Bridging and I/O Aggregation — Use the combination of abundant I/O and on-chip memory for protocol conversion, bus bridging and peripheral aggregation.
• Embedded System Glue Logic — Implement custom state machines, timing-critical interfaces and peripheral controllers that require deterministic logic and local RAM.

Unique Advantages

• Balanced Logic and Memory: 44,000 logic elements with approximately 1.99 Mbits of RAM supports complex control and buffering without external memory in many designs.
• High I/O Count: 245 user I/O pins simplify direct interfacing to sensors, data converters and external controllers, reducing PCB complexity.
• Industrial Readiness: Rated for −40 °C to 100 °C operation, enabling deployment in extended-temperature industrial environments.
• Compact, High-Density Package: 554-FBGA (23×23) surface-mount package allows high integration density for space-constrained boards.
• Controlled Core Voltage: Narrow core supply window (1.045–1.155 V) supports predictable power design and stable operation.
• RoHS Compliant: Meets common environmental assembly requirements for modern electronics production.
