Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. Confirm RoHS compliance status as legacy documentation may vary. Check current availability as this part number may be discontinued or subject to last-time buy restrictions. Ensure the supplier provides original manufacturer packaging to guarantee authenticity and prevent counterfeit risks during acquisition.

Field Programmable Gate Array Selection Notes

Select this model when a balance of moderate logic density and high pin count is required in a QFP package. Compare against ECP3 or ECP5 families if higher speed grades or embedded memory are needed. Verify that the 420 MHz performance meets the timing requirements of the target application. Consider thermal management solutions suitable for the TQFP-144 form factor under maximum load conditions.

Field Programmable Gate Array Part Context

This component belongs to the LatticeECP series, designed for efficiency and innovation in small form factors. It serves as a bridge between lower-end CPLDs and higher-end FPGAs, offering significant logic capacity in a cost-effective package. The ECP family is known for supporting various high-speed serial interfaces and low-power operation modes suitable for diverse embedded applications.

Field Programmable Gate Array Replacement Considerations

Direct substitutes include other devices within the LatticeECP family such as the LFEC20E-3F484C, which shares the same package but may differ in speed grade. Cross-family migration to LatticeECP3 or LatticeECP5 requires schematic and layout redesign due to architectural differences. Always verify pin compatibility and electrical specifications before substituting.
