LFE5UM-25F-7BG381C

The LFE5UM-25F-7BG381C is a commercial-grade Field Programmable Gate Array (FPGA) from the ECP5 family by Lattice Semiconductor Corporation. It implements the ECP5 architecture in a compact 381-FBGA (381-CABGA, 17×17) surface-mount package and is intended for commercial embedded designs.

With 24,000 logic elements, approximately 1.03 Mbits of embedded memory, and up to 197 I/Os, this device targets designs that require moderate logic density, substantial on-chip RAM, and flexible I/O capability while operating from a low-voltage core supply (1.045 V to 1.155 V) over a commercial temperature range (0 °C to 85 °C).

Key Features

• Core Logic  24,000 logic elements provide the programmable fabric for custom logic, state machines, and glue logic implementations.
• Embedded Memory  Approximately 1.03 Mbits of on-chip RAM for data buffering, FIFOs, and local storage without external memory.
• I/O Capacity  Up to 197 user I/Os support broad interfacing options for parallel buses, control signals, and peripheral connections.
• Package & Mounting  381-FBGA (381-CABGA, 17×17) surface-mount package minimizes board footprint while delivering high pin count.
• Power  Low-voltage core supply range of 1.045 V to 1.155 V to match system power-rail constraints.
• Temperature & Grade  Commercial grade device rated for operation from 0 °C to 85 °C.
• Design Architecture (ECP5 Family)  Family-level architecture and features include programmable I/O cells, clocking structures with PLLs, sysMEM memory blocks, sysDSP slices, DDR memory support, SERDES/PCS blocks, and on-chip configuration options as described in the ECP5 family datasheet.
• Regulatory  RoHS compliant.

Typical Applications

• Commercial Embedded Systems  Use the FPGA to implement custom logic, system control, and peripheral interfacing in commercial equipment where a commercial-grade device and compact package are required.
• I/O-Intensive Glue Logic  Bridge and translate between multiple parallel or serialized interfaces using the device’s high I/O count and programmable fabric.
• On-Chip Memory and Buffering  Leverage approximately 1.03 Mbits of embedded RAM for data buffering, packet buffering, and local storage without immediate dependence on external memory.
• High‑Speed Link and Memory Support  Implement DDR memory interfaces and high-speed serial links using family-level DDR and SERDES capabilities documented for the ECP5 series.

Unique Advantages

• High Logic Density: 24,000 logic elements deliver the capacity to consolidate multiple functions into a single FPGA, reducing board-level component count.
• Substantial On-Chip RAM: Approximately 1.03 Mbits of embedded memory enables local data storage and buffering, simplifying memory architecture for many designs.
• Extensive I/O: Up to 197 I/Os provide flexible connectivity for interfacing to peripherals, sensors, buses, and external devices.
• Compact, High-Pin Package: The 381-FBGA (17×17) surface-mount package offers a high pin density in a small footprint suitable for space-constrained boards.
• Low-Voltage Operation: Narrow core supply range (1.045 V–1.155 V) aligns with modern power system designs and allows predictable power planning.
• Commercial-Rated Reliability: Rated for 0 °C to 85 °C operation, matching the needs of commercial product environments.
