• High-density architecture providing 108 macrocells and 81 user I/O pins in a compact form factor.
• Wide operating voltage range from 4.5V to 5.5V suitable for standard 5V logic systems.

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement for discrete TTL or CMOS circuits.
• Address decoding and bus bridging in embedded control systems.
• State machine implementation for industrial automation controllers.
• Interface adaptation between different voltage domains or protocol converters.

Complex Programmable Logic Devices Procurement Notes

This component is officially obsolete and no longer manufactured by AMD. Availability is restricted to existing stock held by distributors or third-party suppliers. Verification of authenticity and lot date codes is critical due to the discontinued status. Buyers should confirm the specific package variant matches their PCB footprint requirements before acquisition.

Complex Programmable Logic Devices Selection Notes

Designers requiring new production should consider modern equivalents from Microchip Technology or Lattice Semiconductor, as the XC9500 series has been superseded. When selecting replacements, ensure pin compatibility and verify that the alternative device meets the required 15 ns speed grade and 5V operating voltage constraints. Review updated datasheets for changes in I/O drive strength and power consumption characteristics compared to the legacy AMD part.

Complex Programmable Logic Devices Part Context

The XC9500 family represents one of the first commercially successful Flash-based CPLD architectures. This series was designed to replace complex discrete logic solutions with a single programmable chip. The XC95108 model specifically targets applications needing moderate logic density with high reliability and ease of use, serving as a bridge between simple PALs and larger FPGAs during the mid-1990s to early 2000s era.

Complex Programmable Logic Devices Replacement Considerations

Microchip ATF1508ASV-15AU100 and Lattice Semiconductor LC95108 are cited as similar alternatives. Verify pinout compatibility and electrical parameters against the original design specifications before substitution.
