Complex Programmable Logic Devices Procurement Notes

This specific part number is obsolete and no longer manufactured. Sourcing requires checking secondary market distributors for surplus stock or identifying pin-compatible alternatives from current CPLD families. Verify RoHS compliance status as original units may not meet modern environmental standards.

Complex Programmable Logic Devices Selection Notes

When selecting a replacement, ensure the substitute device maintains compatibility with the 5V I/O levels required by the existing system design. Verify that the new component supports JTAG programming if in-system reprogramming capabilities are necessary for the application lifecycle.

Complex Programmable Logic Devices Part Context

The XC9500 series represents a high-performance, non-volatile CPLD architecture utilizing EEPROM technology. This family was widely adopted for general-purpose logic applications due to its ease of use, ISP capability, and robust 5V operation, serving as a bridge between discrete logic gates and more complex FPGAs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be available from manufacturers such as Microchip (ATF15xx series) or Lattice (MachXO/LCMXO series). Verify electrical characteristics, particularly VCCIO requirements and package dimensions, before substituting.
