XC9572XL-5VQ64C

Overview

The XC9572XL-5VQ64C is a high-performance, low-voltage Complex Programmable Logic Device (CPLD) from the XC9500XL family. It operates at 3.3V and features four 54V18 function blocks providing 1600 usable gates. The device offers a maximum propagation delay of 5 ns and supports a maximum operating frequency of 178 MHz. It utilizes Flash memory technology for non-volatile configuration and is housed in a 64-pin Quad Flat Pack (VQFP) package with 52 I/O pins.

Feature Summary

• Supports In-System Programmability via Flash memory technology
• Provides high-speed logic performance with 5 ns propagation delay
• Features low voltage operation compatible with 3.3V systems

Applications

• High-performance digital logic replacement
• Interface bridging in communication systems
• Control logic in computing applications

Procurement Notes

This component is officially listed as obsolete and no longer manufactured by AMD/Xilinx. Procurement requires verification of availability through secondary market channels or authorized distributors holding remaining stock. Buyers must confirm the authenticity and condition of units, as new production is unavailable. Parametric equivalents may be considered if supply chain continuity is critical.

Selection Notes

Select this part only when specific timing requirements of 5 ns and 1600 gate capacity are necessary within a 3.3V environment. Ensure the design accommodates the VQFP-64 package footprint. Verify that the application does not require newer architectural features found in successor families, as this model represents an earlier generation of CPLD technology with fixed functionality.

Part Context

The XC9572XL-5VQ64C belongs to the XC9500XL series, designed for cost-effective, high-density logic solutions. It bridges the gap between standard logic gates and complex FPGAs. The device is characterized by its robust Flash-based architecture, allowing for unlimited reprogramming cycles without the need for external configuration devices, making it suitable for standalone logic implementations.

Replacement Considerations

Official substitutes include parametric equivalents such as the XC9572XL-10VQG64C, which shares the same logical structure but differs in speed grade and package type. Users should verify pin compatibility and electrical characteristics before substitution.
