LFE2-20SE-5FN484C

The LFE2-20SE-5FN484C is a Field Programmable Gate Array (FPGA) from Lattice Semiconductor Corporation in the ECP2 family. It provides a programmable logic fabric with 21,000 logic elements, embedded memory and a large I/O complement, packaged for surface-mount assembly in a 484-BBGA footprint.

Designed for commercial-grade applications, this device combines on-chip resources and high I/O density with low-voltage operation (1.14 V to 1.26 V) and an operating temperature range of 0 °C to 85 °C, making it suited for compact board-level digital designs that require significant programmable logic and connectivity.

Key Features

• Core Logic  21,000 logic elements provide the programmable fabric for implementing custom digital functions and control logic.
• Embedded Memory  Approximately 0.28 Mbits of on-chip RAM for buffering, state storage and small data structures within the FPGA.
• I/O Capacity  331 user I/O pins enable extensive external interfacing and signal routing directly to the FPGA.
• Package & Mounting  484-BBGA package (supplier device package: 484-FPBGA, 23×23) in a surface-mount form factor for compact PCB integration.
• Power  Operates from a supply range of 1.14 V to 1.26 V to match low-voltage system rails.
• Temperature & Grade  Commercial-grade device rated for 0 °C to 85 °C operation.
• Environmental Compliance  RoHS compliant for adherence to common environmental requirements.

Typical Applications

• Custom digital logic and prototyping  Use the 21,000 logic elements to implement and iterate bespoke digital functions during development and system integration.
• I/O-intensive interface bridging  The 331 I/O pins accommodate multiple parallel interfaces or gateway functions between system components.
• On-chip buffering and small-data storage  Approximately 0.28 Mbits of embedded RAM supports local buffering, FIFOs and state retention without external memory.
• Compact board designs  The 484-BBGA (23×23) surface-mount package allows high-density placement in space-constrained PCBs.

Unique Advantages

• High logic density: 21,000 logic elements enable implementation of substantial custom logic while keeping design consolidated on a single device.
• Substantial I/O in one package: 331 I/O pins reduce the need for external glue logic when connecting multiple peripherals or interfaces.
• Integrated on-chip memory: Approximately 0.28 Mbits of RAM provides local storage for buffering and control data, simplifying system memory architecture.
• Compact, manufacturable package: 484-BBGA (484-FPBGA, 23×23) surface-mount package supports automated assembly and dense PCB layouts.
• Low-voltage compatibility: Operates at 1.14 V to 1.26 V, aligning with low-voltage system rails and modern digital power domains.
• Commercial temperature rating: Rated for 0 °C to 85 °C operation for mainstream commercial applications.
