Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers. Request original manufacturer documentation or test reports to confirm silicon integrity. Inspect packaging for signs of handling damage. Confirm lot codes match current production batches where applicable. Ensure compliance with RoHS directives if required by system specifications.

Field Programmable Gate Array Selection Notes

Evaluate logic density requirements against the 4,864 available logic cells. Verify I/O count needs do not exceed the 68 available pins in the VQFP-100 package. Check power supply constraints for the 1.2V core requirement. Consider thermal dissipation capabilities of the TQFP/VQFP form factor compared to BGA alternatives.

Field Programmable Gate Array Part Context

This component is part of the Spartan-3A series, designed for cost-sensitive applications. It serves as an upgrade path from the original Spartan-3 family with improved power efficiency. The device targets entry-level programmable logic markets requiring moderate complexity.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitutes include LCMXO2-4000HC-4TG144C from Lattice Semiconductor and T13Q100F3C3 from Efinix. These alternatives offer comparable functionality but may require schematic and bitstream modifications due to architectural differences.
