Procurement Notes

This component is obsolete and no longer manufactured as of August 23, 2021. Verification of availability should focus on surplus distributors or second-source alternatives such as Microchip ATF1504AS or Lattice LC4128V series devices. Ensure RoHS compliance status is reviewed, as original units may not meet current environmental standards.

Selection Notes

Select this part for designs requiring moderate I/O density with non-volatile configuration retention. Verify that the 84-pin PQFP footprint matches the PCB layout. Confirm that the 5V supply rail aligns with the 4.75V–5.25V operating range. Consider thermal dissipation limits for the PQFP package under continuous load conditions.

Part Context

The XC9500 family represents a high-performance CPLD architecture utilizing EEPROM technology for non-volatile storage. This specific model integrates standard JTAG interface support for boundary scan testing and programming. It serves as a bridge between simple gate arrays and more complex FPGA solutions, offering deterministic timing and ease of design implementation.

Replacement Considerations

Publicly confirmed substitute part numbers include Microchip Technology ATF1504AS-7AX100 and Lattice Semiconductor Corporation LC4128V-75TN100C. These alternatives offer similar macrocell counts and pin compatibility but may require verification of electrical characteristics and package dimensions.
