Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'E' against official Lattice documentation to confirm it denotes the standard commercial/industrial variant distinct from the 'EA' extended performance series. Ensure the ordering part number matches the exact speed grade '-7' and package type 'FN672I'. Confirm RoHS compliance status through the manufacturer's current product selector guide or datasheet revision history before procurement.

Field Programmable Gate Array Selection Notes

Select this model when designing systems requiring moderate logic density with high-speed serial connectivity options. The 67k LE capacity suits complex bridging and control tasks. Verify that the 672-pin footprint fits the PCB layout constraints. Compare power consumption estimates against thermal limits for the target enclosure. Consider the availability of development tools like Diamond Programmer for configuration.

Field Programmable Gate Array Part Context

This component belongs to the Lattice ECP3 family, which targets low-power, high-reliability applications in industrial, automotive, and communications sectors. The ECP3 series is characterized by its efficient architecture combining DSP blocks with robust I/O capabilities. It serves as a bridge between different interface standards while maintaining low energy consumption compared to larger FPGA families.

Field Programmable Gate Array Replacement Considerations

LFE3-70EA-7FN672I: Check if the 'EA' suffix indicates higher performance or extended specifications that are compatible with the design requirements. LFE3-95EA-7FN672I: Offers higher logic density but may require verification of pin compatibility and power budget adjustments.
