LFE5UM-45F-7BG554C

The LFE5UM-45F-7BG554C is a commercial-grade FPGA device in the Lattice ECP5 family. It provides a mid-range fabric with 44,000 logic elements, approximately 1.99 Mbits of embedded RAM, and a high I/O count for complex, I/O-rich commercial embedded designs.

Built on the ECP5 family architecture, this device targets applications that require a balance of logic capacity, on-chip memory, programmable I/O, and SERDES/clocking resources as described in the ECP5 family datasheet.

Key Features

• Logic Capacity – 44,000 logic elements provide substantial programmable logic resources for mid-range FPGA designs.
• Embedded Memory – Approximately 2.0 Mbits of on-chip RAM (1,990,656 bits) for buffering, packet storage, or small lookup tables.
• I/O – 245 user I/O pins support dense interfacing and front-end connectivity in I/O-heavy designs.
• Family-Level Architecture – Part of the ECP5 family, which includes features such as programmable I/O cells, sysDSP slices, SERDES and PCS blocks, flexible clocking (sysCLOCK PLL and clock distribution), and DDR memory support per the ECP5 family datasheet.
• Configuration & System Blocks – Enhanced configuration options, on-chip oscillator, and single-event upset (SEU) support are included in the ECP5 family documentation.
• Package & Mounting – 554-ball FBGA package (supplier device package 554-CABGA, 23×23), suitable for surface-mount PCB assembly.
• Power – Core supply operating range of 1.045 V to 1.155 V for integration into modern power-rail environments.
• Operating Conditions – Commercial temperature grade with an operating range of 0 °C to 85 °C.
• Environmental – RoHS compliant.

Typical Applications

• Commercial Embedded Systems – Implement mid-density control and processing logic where commercial temperature operation and a balance of logic and memory are required.
• I/O-Intensive Interface Modules – Use the 245 I/Os and programmable I/O cells for protocol bridging, board-level aggregation, or multi-channel front-end connectivity.
• Memory and Interface Controllers – Leverage on-chip RAM and ECP5 family DDR support for buffering, memory controllers, and data path staging.
• DSP and Signal Processing – Employ sysDSP slices (as described in the ECP5 family datasheet) for embedded arithmetic and signal-processing tasks within commercial applications.

Unique Advantages

• High Logic Density: 44,000 logic elements enable complex mid-range designs without requiring higher-tier devices.
• Generous I/O Availability: 245 user I/Os simplify system integration and reduce the need for external I/O expanders.
• Integrated Memory Resources: Approximately 2.0 Mbits of embedded RAM reduces external memory dependence for many buffering and control tasks.
• Family-Level System Blocks: ECP5 family features such as programmable I/O, sysDSP, SERDES, and flexible clocking provide building blocks for common application needs.
• Compact, Surface-Mount Package: 554-FBGA (554-CABGA 23×23) provides a high-pin-count solution in a compact footprint for dense PCB layouts.
• Commercial Temperature and RoHS Compliance: Commercial operating range (0 °C to 85 °C) and RoHS compliance support broad commercial deployment.
