Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers due to the part's discontinued status. Confirm RoHS compliance requirements as this specific model may not meet current environmental standards. Validate package integrity and pin alignment prior to integration into printed circuit board assemblies.

Field Programmable Gate Array Selection Notes

Evaluate the trade-off between the 20,000 gate count and available I/O pins against project requirements. Consider the 3V operating voltage compatibility with existing system power rails. Assess thermal management needs for the 0°C to 85°C commercial grade specification during final enclosure design.

Field Programmable Gate Array Part Context

This component belongs to the Spartan-XL family, representing an evolution of Xilinx's early low-cost FPGA technology. It succeeded earlier Spartan models by offering increased density and improved performance metrics while maintaining cost-effectiveness for mass-market electronic applications.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed direct substitute part numbers are not available. Designers should consult official obsolescence notices for recommended migration paths to modern FPGA families with equivalent resource counts.
