LFE5UM-85F-6BG381C

The LFE5UM-85F-6BG381C is an ECP5-family FPGA from Lattice Semiconductor, offering mid-range programmable logic capacity in a compact 381-ball FBGA package. It combines programmable logic, on-chip memory, and flexible I/O in a surface-mount 17 × 17 mm CABGA footprint for commercial embedded and communications applications.

Designed for systems that require significant logic density, embedded RAM and a broad I/O count, this device targets applications where integration and form factor matter while operating within a commercial temperature range.

Key Features

• Logic Capacity — Approximately 84,000 logic elements suitable for mid-density FPGA designs and moderate compute pipelines.
• Embedded Memory — Approximately 3.8 Mbits of on-chip RAM to support frame buffers, packet buffering, and local data storage without external memory for many use cases.
• I/O Resources — 205 general-purpose I/Os to support a mix of peripheral interfaces and high-pin-count designs.
• Clocking and Timing — ECP5 family documentation includes clock management features such as sysCLOCK PLLs and clock distribution networks for flexible timing architectures.
• High-speed Interfaces — ECP5 family features SERDES and DDR memory support as described in the family datasheet, enabling interface bridging and higher-bandwidth links when required.
• Package and Mounting — 381-ball FBGA (supplier package: 381-CABGA, 17×17 mm) in a surface-mount form factor to minimize PCB area.
• Power Supply — Core supply range specified from 1.045 V to 1.155 V; suitable for designs targeting low-voltage core operation.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operating temperature.
• Compliance — RoHS-compliant component.

Typical Applications

• Communication and Networking Equipment — Use the device for interface bridging, protocol conversion and mid-range packet processing leveraging its logic density and SERDES/DDR capabilities (ECP5 family).
• Video and Imaging Subsystems — On-chip RAM and plentiful I/O make it suitable for buffering, preprocessing and format conversion tasks in commercial AV equipment.
• Test & Measurement — Implement custom data acquisition, signal conditioning logic and deterministic processing pipelines using the FPGA’s logic and memory resources.
• Embedded Systems and Prototyping — Ideal for developers needing a compact, reprogrammable platform with substantial I/O for add-on peripherals and sensors.

Unique Advantages

• Substantial Logic Density: Approximately 84,000 logic elements provide a balance of capacity and cost for mid-range designs.
• Integrated On-Chip Memory: Approximately 3.8 Mbits of embedded RAM reduces the need for external memory in many buffering and storage use cases.
• High I/O Count: 205 I/Os enable connectivity to multiple peripherals and parallel interfaces without immediate external I/O expanders.
• Compact, Surface-Mount Package: 381-CABGA (17×17) package minimizes PCB footprint while providing high pin density.
• Narrow Core Voltage Window: Core supply specified between 1.045 V and 1.155 V supports consistent low-voltage operation when integrated into modern power rails.
• Commercial Temperature Rating and RoHS Compliance: Suited for a wide set of commercial products while meeting RoHS environmental requirements.
