Complex Programmable Logic Devices Procurement Notes

This specific part number is officially obsolete and no longer manufactured by AMD. Procurement must rely on secondary market distributors or verified surplus stock. Verify RoHS compliance status, as older XC9500 variants may not meet current environmental regulations. Confirm package integrity and pin condition when sourcing from non-OEM channels due to the component's discontinued status.

Complex Programmable Logic Devices Selection Notes

Designers requiring new production should select modern equivalents from Lattice Semiconductor or Xilinx families, as the XC9500 series lacks current manufacturing support. Consider packages with higher pin counts if additional I/O is required, noting that the XC95108 provides 108 I/O pins. Ensure voltage requirements align with standard 5V logic levels, as this device does not support lower voltage operation natively.

Complex Programmable Logic Devices Part Context

The XC95108-15PQ160C is part of the AMD XC9500 CPLD family, which utilizes Flash memory technology for non-volatile configuration. This architecture allows for unlimited reprogramming without the need for UV erasure. The XC9500 series was widely adopted for its ease of use and ISP capabilities, serving as a bridge between simple PALs and more complex FPGAs in legacy and industrial designs.

Complex Programmable Logic Devices Replacement Considerations

Lattice Semiconductor LC4128V-75TN144C is listed as a similar alternative. Note that the substitute uses a 144-pin TQFP package compared to the original's 160-pin PQFP, requiring PCB layout modifications. Verify pin compatibility and logic density differences before substitution.
