LFE2-20E-5F256C

The LFE2-20E-5F256C is a commercial-grade ECP2 family field programmable gate array from Lattice Semiconductor Corporation. It delivers 21,000 logic elements and approximately 0.28 Mbits of on-chip RAM in a compact 256-ball fpBGA (17 × 17 mm) package, making it suitable for a wide range of commercial embedded and connectivity designs.

With 193 general-purpose I/Os, programmable I/O buffering, on-chip clock management and family-level support for DSP and flexible memory resources, this device is aimed at designs that require medium-density logic integration, moderate memory, and broad I/O flexibility.

Key Features

• Core Logic — 21,000 logic elements for implementing complex digital functions and mid-density system integration.
• Embedded Memory — 282,624 total RAM bits (approximately 0.28 Mbits) of on-chip memory for buffering, FIFOs and local storage.
• I/O Capacity — 193 user I/Os delivered from the 256-ball fpBGA package to support multiple interfaces and board-level signal routing.
• Programmable sysI/O — Family-level programmable I/O buffer support for a wide range of standards, enabling flexible interfacing to legacy and modern peripherals.
• Clock Management — Integrated clock resources consistent with the ECP2 family (general-purpose PLLs and DLLs) to support system timing and clock domain management.
• Package & Mounting — 256-FPBGA (17 × 17 mm) surface-mount package for compact board footprint and high pin density.
• Power — Low-voltage core supply range of 1.14 V to 1.26 V.
• Operating Range & Grade — Commercial grade operation with an ambient temperature range of 0 °C to 85 °C.
• Compliance — RoHS compliant.
• Design Support — Supported by the Lattice ECP2 family documentation and design tools referenced in the product datasheet for device configuration and implementation.

Typical Applications

• Commercial Embedded Systems — Implement mid-density control, glue logic and protocol conversion for consumer and commercial products where a commercial-grade FPGA is appropriate.
• DSP Acceleration — Leverage the ECP2 family’s sysDSP resources for multiply-accumulate and signal-processing tasks in communications and signal conditioning designs.
• Memory Interfaces and Buffering — Use on-chip RAM and dedicated I/O register structures to implement DDR/DDR2 interfacing, buffering and data alignment functions.
• I/O-Intensive Glue Logic — 193 I/Os enable protocol bridging, board-level aggregation and dense peripheral interfacing for complex systems.

Unique Advantages

• Balanced Logic and Memory: 21,000 logic elements combined with ~0.28 Mbits of embedded RAM provide a balance of compute and local storage for mid-size designs.
• High I/O Count in a Compact Package: 193 I/Os in a 256-ball fpBGA (17 × 17 mm) allow dense connectivity without a large PCB footprint.
• Low Core Voltage: 1.14–1.26 V core supply supports low-power core operation suitable for power-sensitive commercial applications.
• Commercial Temperature Qualification: Rated for 0 °C to 85 °C operation, matching typical commercial product deployment requirements.
• RoHS Compliance: Meets lead-free and restricted materials requirements for modern electronics manufacturing.
• Established Design Ecosystem: Family datasheet and tool support streamline integration, configuration and system bring-up.
