Field Programmable Gate Array Procurement Notes

This specific part number is listed as discontinued in public databases. Verification of availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should confirm the final status with Lattice Semiconductor directly, as discontinuation may impact long-term supply chain stability and replacement sourcing.

Field Programmable Gate Array Selection Notes

When selecting this component, verify that the TQFP-144 package fits the board layout constraints, specifically the 20x20 mm footprint and 0.5 mm pitch. Ensure the design environment supports the legacy ECP family tools if migration to newer platforms like ECP5 is not planned. Confirm that the 1.2V core voltage requirement aligns with the system's power delivery network capabilities.

Field Programmable Gate Array Part Context

The LFEC6E-4F484C belongs to the Lattice ECP series, which was designed for cost-effective connectivity and acceleration applications. This specific variant represents a lower-density option within the ECP lineup, offering 768 CLBs. It serves as a predecessor to later generations such as the ECP3 and ECP5 families, which expanded resource counts and added advanced features like embedded SERDES.

Field Programmable Gate Array Replacement Considerations

Public documentation lists this part as discontinued. Potential functional replacements within the same logical density class include other ECP variants or migration to the MachXO3 or ECP5 families, depending on I/O and performance requirements. Verify pin-to-pin compatibility and toolchain support before substituting.
