LFE5UM-45F-6BG554I

The LFE5UM-45F-6BG554I is an ECP5-family field programmable gate array (FPGA) manufactured by Lattice Semiconductor Corporation. It provides a programmable logic fabric with 44,000 logic elements and embedded memory, delivered in a 554-ball FBGA package.

Designed for industrial-grade operation, this device offers broad I/O capacity and on-chip resources suitable for designs that require integrated programmable logic, memory, and serial/parallel interfacing within a compact surface-mount package.

Key Features

• Logic Capacity  44,000 logic elements (cells) to implement combinational and sequential logic functions.
• Embedded Memory  Approximately 1.99 Mbits of total on-chip RAM for FIFOs, buffers, and storage directly inside the FPGA fabric.
• I/O Density  245 general-purpose I/Os to support extensive peripheral and bus connectivity without immediate need for external expanders.
• Industrial Temperature Range  Qualified for –40 °C to 100 °C operation for deployment in industrial environments.
• Supply Voltage  Core voltage range of 1.045 V to 1.155 V to match system power rails and design constraints.
• Package and Mounting  554-ball FBGA (554-CABGA, 23 × 23 mm) surface-mount package providing a high-pin-count, compact footprint.
• RoHS Compliant  Manufactured in compliance with RoHS requirements.

Typical Applications

• Memory Interface and Buffering  On-chip RAM and I/O bank capacity support DDR/parallel memory buffering and interface logic.
• High‑I/O Control and Glue Logic  Large I/O count enables aggregation of sensors, peripherals, and control buses in embedded systems.
• Serial Connectivity and SERDES Integration  ECP5-family architecture and datasheet coverage of SERDES and PCS make the device suitable where serial link elements are required.
• DSP and Signal Processing Blocks  Embedded DSP-oriented slices documented in the family datasheet support arithmetic and signal-processing tasks inside the FPGA fabric.

Unique Advantages

• High integration density: 44,000 logic elements combined with ~1.99 Mbits of on-chip RAM reduce reliance on external logic and memory components.
• Extensive I/O capability: 245 I/Os provide flexibility for complex board-level interfacing and multiple parallel/serial connections.
• Industrial readiness: Rated for –40 °C to 100 °C operation to meet the environmental demands of industrial applications.
• Compact, high-pin package: 554-ball FBGA (23 × 23 mm) offers a dense pinout in a compact surface-mount form factor.
• Controlled core power range: Narrow core supply window (1.045 V–1.155 V) supports predictable power design and rail management.
• Standards-compliant manufacturing: RoHS compliance aligns with regulatory and environmental requirements.
