LFE2-20E-5F484C

The LFE2-20E-5F484C is a field-programmable gate array (FPGA) from Lattice Semiconductor designed for embedded logic and I/O-intensive designs. It provides a balance of programmable logic capacity, on-chip memory, and a high I/O count in a compact ball-grid array package suitable for commercial applications.

With 21,000 logic elements, approximately 0.28 Mbits of embedded memory, and up to 331 I/O pins, this device targets designs that require substantial customizable logic, dense interfacing, and low-voltage operation within a commercial temperature range.

Key Features

• Core Logic — 21,000 logic elements to implement custom digital functions and glue logic.
• Embedded Memory — Approximately 0.28 Mbits (282,624 bits) of on-chip RAM for buffering, FIFOs, and small data structures.
• I/O Density — 331 user I/O pins to support multiple interfaces and parallel connections.
• Power — Supports a supply voltage range of 1.14 V to 1.26 V for low-voltage system designs.
• Package — 484-ball BGA in a 484-FPBGA (23×23) form factor (package case: 484-BBGA) for high pin-count, compact board integration.
• Mounting & Grade — Surface-mount device rated for commercial temperature operation from 0°C to 85°C.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Protocol Bridging and Interface Conversion — Use the high I/O count and programmable logic to implement custom protocol adapters and signal translators.
• Custom Logic and Glue Logic — Deploy the 21,000 logic elements to consolidate discrete logic, timing control, and specialized data paths.
• Embedded Data Buffering — Leverage approximately 0.28 Mbits of embedded RAM for buffering, FIFOs, and temporary storage in data-flow designs.

Unique Advantages

• High Logic Capacity: 21,000 logic elements provide room for complex combinational and sequential logic without external ASICs.
• Substantial I/O Availability: 331 I/O pins allow multiple peripherals and parallel interfaces to be routed directly to the FPGA.
• Compact High-Pin Package: 484-BBGA (484-FPBGA, 23×23) delivers high pin count in a compact footprint for dense PCB layouts.
• Low-Voltage Operation: Operates from 1.14 V to 1.26 V, enabling integration into low-voltage power domains.
• Commercial Temperature Range: Rated 0°C to 85°C for standard commercial deployments.
• RoHS Compliant: Meets environmental compliance requirements for lead-free assembly.
