XC9572XL-10VQ64C

Complex Programmable Logic Devices Overview

The XC9572XL-10VQ64C is a Complex Programmable Logic Device (CPLD) belonging to the AMD XC9500 family. It features 72 macrocells and supports up to 54 user I/O pins within a 64-pin VQFP package. The device operates at a supply voltage of 4.75V to 5.25V and offers a maximum propagation delay of 10ns. It utilizes In-System Programmability (ISP) via JTAG, allowing for non-volatile configuration with over 10,000 erase/program cycles. The component is designed for commercial temperature ranges from 0°C to 70°C.

Complex Programmable Logic Devices Feature Summary

• 72 Macrocells with 1600 usable system gates
• In-System Programmability via IEEE 1149.1 JTAG interface
• High-speed performance with 10ns maximum propagation delay
• Non-volatile Flash technology supporting 10,000+ program/erase cycles

Complex Programmable Logic Devices Applications

• Logic replacement for legacy TTL/CMOS circuits
• Address decoding and bus bridging in embedded systems
• State machine implementation for industrial control
• Clock buffering and distribution

Complex Programmable Logic Devices Procurement Notes

Verify RoHS compliance status as older XC9500 variants may not meet current environmental standards. Confirm package integrity upon receipt, as VQFP leads are susceptible to bending during handling. Ensure programming cables support the specific voltage levels required for ISP operations on this generation of CPLDs.

Complex Programmable Logic Devices Selection Notes

Select the XC9572XL variant when higher speed (10ns vs 15ns) is required compared to the standard XC9572. Choose the VQ64 package for surface-mount applications requiring a compact footprint with 54 accessible I/Os. Verify that the design toolchain supports the XC9500XL architecture for accurate timing analysis and place-and-route results.

Complex Programmable Logic Devices Part Context

This component is part of the enhanced XC9500XL series, which introduced Flash memory technology to replace the earlier EPROM-based XC9500 devices. This transition enabled true In-System Programmability without UV erasure, significantly simplifying manufacturing and field updates for logic integration designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to architectural differences. Consider Microchip ATF15xx series or Lattice LC4000 series for functional equivalents, though logic capacity and I/O configurations must be carefully mapped to ensure compatibility.
