Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is restricted to limited stock or surplus channels. Verification of authenticity and lot traceability is critical when sourcing from third-party distributors due to the discontinued status.

Selection Notes

Select this part for designs requiring low pin counts and simple programmable logic. Ensure the design voltage matches the 3.0V–3.6V range. Consider the 5.5 ns propagation delay for timing closure. Verify if the VQFP-100 package fits the PCB footprint constraints.

Part Context

Part of the XCR3000XL family, which offers high-density CPLDs with fast performance. This specific model represents a mid-range density option within the series, balancing I/O count and macrocell resources for cost-sensitive applications.

Replacement Considerations

Check for direct pin-compatible upgrades within the XCR3000XL series, such as higher speed grades or larger packages. Cross-reference with newer AMD/Xilinx CPLD families if long-term supply assurance is required.
