Procurement Notes

Verify component authenticity as this part number may be subject to discontinuation notices. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Check for specific suffix variations that may indicate temperature range or packaging differences.

Selection Notes

Select this model for applications requiring 34 I/Os in a compact PLCC footprint. Ensure design compatibility with 3.3V logic levels and verify that the 7.5 ns timing meets system requirements. Consider alternative packages like VQFP if leaded-free surface mount is preferred.

Part Context

This component belongs to the XC9500XL series, an evolution of the XC9500 line offering higher performance and lower power consumption. It is designed for general-purpose digital logic applications where reprogrammability and high density are required.

Replacement Considerations

Direct pin-to-pin replacements may not exist due to proprietary architecture. Evaluate Microchip ATF15xx series or Lattice ispLSI series for functional equivalents, ensuring gate count and I/O compatibility.
