Complex Programmable Logic Devices Procurement Notes

Verify component authenticity due to discontinuation status. Confirm RoHS compliance requirements as original versions may not meet current standards. Check for moisture sensitivity level (MSL 3) handling precautions during storage and assembly. Ensure supplier documentation matches the specific speed grade and temperature variant.

Complex Programmable Logic Devices Selection Notes

Select this model when 72 macrocells are sufficient for the design logic. Choose the -15 speed grade if timing constraints allow for 15 ns delays. Opt for the PC84 package if board space accommodates an 84-pin PLCC footprint. Verify that the system power supply strictly maintains the 4.75V to 5.25V range for correct operation.

Complex Programmable Logic Devices Part Context

This part is a member of the Xilinx XC9500 CPLD family, acquired by AMD. It serves as a drop-in replacement for older GALs and PALs. The XC9500 series was widely used for low-density logic functions before being succeeded by the XC9500XL and XC9500XV families.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements are limited. Consider Lattice Semiconductor LC4000 or ATtiny series devices after verifying pinout compatibility and electrical specifications. Review datasheets for differences in VCCIO requirements and programming interfaces.
