LFE2-20E-5F672C

The LFE2-20E-5F672C is an ECP2 Field Programmable Gate Array from Lattice Semiconductor Corporation, offering a balance of logic capacity, I/O density, and on-chip memory for commercial embedded applications. Its architecture provides 21,000 logic elements, 402 user I/O pins, and approximately 0.28 Mbits of embedded memory, packaged in a compact 672-BBGA surface-mount package.

Designed for systems operating on low core voltages, this FPGA supports a supply range of 1.14 V to 1.26 V and is specified for commercial temperature operation from 0 °C to 85 °C. It is RoHS compliant for environmental compatibility.

Key Features

• Core Logic  21,000 logic elements provide capacity for moderate-complexity combinational and sequential logic implementations.
• Embedded Memory  Approximately 0.28 Mbits of on-chip RAM suitable for buffering, small FIFOs, and lookup tables.
• I/O Density  402 user I/O pins enable extensive peripheral and bus interfacing on a single device.
• Package  672-BBGA package (supplier device package: 672-FPBGA, 27×27) supports dense board layouts while maintaining a surface-mount form factor.
• Power  Core supply voltage range of 1.14 V to 1.26 V for compatibility with low-voltage system rails.
• Temperature & Grade  Commercial grade device rated for operation from 0 °C to 85 °C.
• Environmental Compliance  RoHS compliant for restriction of hazardous substances.

Typical Applications

• Embedded Control and Glue Logic  Use the 21,000 logic elements and abundant I/O to integrate custom control functions and interface glue on commercial products.
• High-Density Peripheral Interfacing  402 I/O pins enable aggregation and routing of multiple peripherals and buses within a compact package footprint.
• On-Chip Data Buffering  Approximately 0.28 Mbits of embedded RAM supports small buffering and temporary data storage for data flow and protocol handling.
• Compact, High-Integration Board Designs  The 672-BBGA surface-mount package allows for space-efficient placement in designs where board area and pin count are critical.

Unique Advantages

• High Logic Capacity: 21,000 logic elements let you implement substantial custom logic without external gate arrays or CPLDs.
• Extensive I/O Count: 402 user I/O pins reduce the need for external multiplexers or expanders when connecting multiple peripherals.
• On-Board Memory: Approximately 0.28 Mbits of embedded RAM provides local storage for buffering and state machines, simplifying system design.
• Compact BGA Package: The 672-BBGA (672-FPBGA, 27×27) supports dense routing and minimizes PCB footprint for space-constrained applications.
• Low-Voltage Core Compatibility: Operates from 1.14 V to 1.26 V to match modern low-voltage system rails.
• Commercial Grade with RoHS Compliance: Rated for 0 °C to 85 °C and RoHS compliant for deployment in commercial product lines.
