LFE5UM5G-25F-8BG381C

The LFE5UM5G-25F-8BG381C is an ECP5-5G family FPGA from Lattice Semiconductor, offered in a 381-FBGA (381-CABGA, 17×17) surface-mount package. It provides a mid-range programmable fabric with 24,000 logic elements, approximately 1.03 Mbits of embedded RAM, and 197 general-purpose I/O pins for dense I/O and logic integration.

Targeted at commercial-temperature applications (0 °C to 85 °C), the device combines a compact package and a narrow core supply range (1.045 V to 1.155 V) for designs that require moderate logic capacity, significant on-chip RAM, and a high pin-count in a small footprint.

Key Features

• Logic Capacity  24,000 logic elements provide the programmable fabric required for mid-density logic, control and glue-logic tasks.
• Embedded Memory  Approximately 1.03 Mbits of on-chip RAM suitable for buffering, LUT-based storage and small data structures.
• I/O and Packaging  197 I/O pins in a 381-FBGA (381-CABGA, 17×17) surface-mount package enable high-density external interfacing while keeping a compact board footprint.
• Power and Operating Range  Core supply range of 1.045 V to 1.155 V and commercial operating temperature range of 0 °C to 85 °C for general-purpose electronics.
• Family Architecture (series-level)  Series documentation for the ECP5/ECP5-5G family describes architecture elements such as programmable I/O cells, PLL-based clocking, sysMEM memory blocks, sysDSP slices, SERDES and DDR memory support—useful reference material for system-level design.
• Environmental Compliance  RoHS-compliant construction supports regulatory requirements for lead-free assemblies.

Typical Applications

• Embedded Systems  Use as a configurable logic and I/O hub for embedded controllers, protocol bridging, and application-specific logic.
• Communications Equipment  Leverage the device's high I/O count and series-level SERDES and clocking features for interface handling and data-path conditioning.
• Consumer and Industrial Electronics (Commercial Grade)  Enable feature-rich consumer products and commercial equipment that require mid-density FPGA logic, on-chip RAM and plentiful I/O in a compact package.
• Test and Measurement  Implement custom signal processing, data capture and I/O routing functions using the device's logic fabric and embedded memory.

Unique Advantages

• Balanced Logic and Memory: 24,000 logic elements paired with approximately 1.03 Mbits of embedded RAM allow a mix of control, data buffering and small compute blocks on-chip.
• High I/O Density in a Compact Package: 197 I/Os in a 381-FBGA (17×17) provide extensive external connectivity without a large PCB footprint.
• Commercial-Grade Thermal Range: Rated for 0 °C to 85 °C, suitable for a wide range of general-purpose electronic products and commercial deployments.
• Narrow Core Voltage Window: Defined core supply range (1.045 V to 1.155 V) supports predictable power budgeting and supply design.
• RoHS Compliance: Environmentally compliant construction simplifies assembly and regulatory considerations.
• Documented Family Features: Series-level datasheet material provides architectural guidance (clocking, memory, programmable I/O, SERDES and configuration), aiding system integration and design planning.
