Complex Programmable Logic Devices Procurement Notes

This component is officially obsolete and no longer manufactured by AMD. Sourcing is limited to existing stock from distributors or third-party suppliers. Verify authenticity carefully due to potential surplus market availability. Check for RoHS compliance status, as original production may not meet current environmental regulations. Confirm package condition and pin integrity before integration into new designs.

Complex Programmable Logic Devices Selection Notes

Designers should consider this part only for legacy maintenance or specific form-factor requirements where the 100-TQFP package is mandatory. For new designs, evaluate modern equivalents from Microchip or Lattice that offer similar gate counts and I/O configurations. Ensure voltage levels match the 4.75V–5.25V requirement. Verify timing constraints against the 15 ns maximum delay specification.

Complex Programmable Logic Devices Part Context

The XC95108 is part of the AMD XC9500 CPLD family, which utilizes Flash memory technology for non-volatile configuration. This family was widely adopted for low-power, high-density logic applications before being superseded by newer architectures. The XC95108 specifically offers a balance of density and speed suitable for mid-range logic control tasks.

Complex Programmable Logic Devices Replacement Considerations

Microchip ATF1508ASV-15AU100 is listed as a similar alternative. Lattice Semiconductor also provides compatible options within the same performance class. Verify pinout compatibility and electrical specifications when substituting.
