Field Programmable Gate Array Procurement Notes

Verify the specific suffix '7' indicates the -7 speed grade when sourcing replacements. Confirm the FN484C designation matches the required 484-pin FineLine BGA package type. Ensure the manufacturer is identified as Lattice Semiconductor Corporation to avoid confusion with legacy EC family parts. Cross-reference the RoHS compliance status if environmental regulations apply to your assembly process.

Field Programmable Gate Array Selection Notes

Select this component when a balance between moderate logic density and high I/O count is required. The ECP2 architecture offers lower power consumption compared to older FPGA families while maintaining competitive performance. Consider the 484-pin footprint constraints during PCB layout planning. Evaluate the 1.2V operating voltage against available power rails in the target system design.

Field Programmable Gate Array Part Context

This part belongs to the Lattice ECP2 family, which succeeded the original EC series. It provides enhanced logic resources and memory capacity over previous generations like the LFEC15E. The ECP2 series is known for its cost-effective solution for mid-range FPGA applications requiring significant I/O connectivity.

Field Programmable Gate Array Replacement Considerations

LFE2-50E-5FN484C: Same package and logic density but slower speed grade (-5 vs -7). LFE2-35E-7FN484C: Lower logic density (32k ALMs) but same speed and package.
