The LFE5UM5G-45F-8BG381I is an ECP5-5G family FPGA from Lattice Semiconductor Corporation. It delivers a mid-range programmable logic resource set including 44,000 logic elements, approximately 1.99 Mbits of embedded RAM, and 203 I/O pins in a compact 381-FBGA (381-CABGA 17×17) surface-mount package.

Designed for embedded and industrial applications, the device provides programmable logic, on-chip memory, SERDES and DDR support, and clocking/DSP resources described in the ECP5/ECP5-5G family datasheet, while operating from a 1.045–1.155 V core supply and across an industrial temperature range of −40 °C to 100 °C. The device is RoHS compliant.

Key Features

• Core Logic – 44,000 logic elements provide the programmable fabric for control, glue logic, and mid-range logic integration.
• Embedded Memory – Approximately 1.99 Mbits of on-chip RAM (total RAM bits: 1,990,656) for frame buffering, FIFOs, and state storage.
• I/O Resources – 203 user I/Os supported by programmable I/O cells as described in the family datasheet, enabling diverse interface requirements.
• Clocking and DSP – Family-level architecture includes sysCLOCK PLLs and sysDSP slices for clock management and signal processing (see family datasheet for details).
• SERDES and DDR Support – Device documentation for the ECP5/ECP5-5G family includes SERDES blocks and DDR memory support for high-speed serial and memory interfaces.
• Power – Core supply voltage range of 1.045 V to 1.155 V to match low-voltage system designs.
• Package & Mounting – 381-FBGA (381-CABGA 17×17) surface-mount package for board-level integration in space-constrained designs.
• Operating Range & Compliance – Industrial operating temperature from −40 °C to 100 °C and RoHS compliance for regulatory alignment.

Typical Applications

• High-speed serial interfaces – SERDES capability in the ECP5-5G family supports protocol bridging and serialized data links.
• Memory interface and buffering – DDR memory support and on-chip sysMEM blocks provide buffering and interfacing for external memories.
• DSP and signal processing – sysDSP slice resources enable embedded signal processing tasks and fixed-function arithmetic acceleration.
• Embedded control and I/O aggregation – 203 I/Os and programmable I/O cells allow consolidation of control, sensor, and peripheral interfaces.

Unique Advantages

• High logic density: 44,000 logic elements allow consolidation of multiple functions into a single device.
• Substantial on-chip RAM: Approximately 1.99 Mbits of embedded memory reduces dependence on external buffering for many designs.
• Flexible interface support: 203 I/Os combined with documented SERDES and DDR support provide broad connectivity options.
• Industrial-ready thermal range: −40 °C to 100 °C supports deployment in industrial environments.
• Low-voltage core operation: 1.045–1.155 V core supply aligns with modern low-voltage system architectures.
• Compact, board-ready package: 381-FBGA (17×17) surface-mount package simplifies PCB layout for space-constrained applications.
