Complex Programmable Logic Devices Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Availability is limited to surplus or secondary market channels. Verify RoHS compliance status through specific datasheet revisions before integration. Supply chain lead times may vary significantly due to discontinued status. Confirm package authenticity and pin integrity upon receipt.

Complex Programmable Logic Devices Selection Notes

Select this part for low-density logic applications requiring non-volatile configuration without external PROMs. The 7.5 ns delay suits moderate-speed digital interfaces. Ensure design compatibility with 3.3V logic levels. Consider pin count constraints as the VQFP-44 offers 34 usable I/Os. Evaluate thermal dissipation within the specified -40°C to +85°C range for final enclosure design.

Complex Programmable Logic Devices Part Context

Part of the XC9500XL series, an enhanced version of the original XC9500 CPLD family. The XL variant offers lower power consumption and higher speed compared to predecessors. It serves as a drop-in replacement for legacy E²PROM-based CPLDs in many designs while providing improved performance metrics and reduced static power draw.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same family include XC9572XL-7TQ100I (different package) or XC9572XL-7VQ44C (commercial grade). For functional equivalents from other vendors, consider Lattice ispMACH 4000ZE series devices with comparable macrocell counts.
