XC9572XV-5PC44C

Complex Programmable Logic Devices Overview

XC9572XV-5PC44C is a Complex Programmable Logic Device (CPLD) from the XC9500XL series, manufactured by AMD (formerly Xilinx). It utilizes FastFLASH non-volatile technology and operates at 5V. The device features 72 macrocells and 1600 system gates within four 36x18 function blocks. The '-5' suffix indicates a maximum pin-to-pin propagation delay of 5 nanoseconds. It is housed in a 44-pin PLCC package with a commercial temperature range of 0°C to +70°C. Key specifications include support for up to 10,000 programming/erase cycles and an internal frequency capability of approximately 222 MHz.

Complex Programmable Logic Devices Feature Summary

• Supports In-System Programming (ISP) via JTAG boundary scan interface without removing the device from the circuit.
• Features enhanced pin-locking architecture allowing flexible placement of I/O pins on any available package pin.
• Includes user-programmable ground pins and independent output slew rate control for optimized signal integrity.
• Provides design security through extended safety features and programmable power-down modes.

Complex Programmable Logic Devices Applications

• High-speed digital logic replacement for legacy TTL or CMOS circuits.
• Address decoding and bus bridging in embedded systems.
• State machine implementation for motor control and industrial automation.
• Interface translation between different voltage domains or protocol standards.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity carefully as this part may be obsolete. Check for date codes and packaging integrity. Ensure compatibility with existing PCB footprints and programming cables. Confirm that the specific speed grade (-5) meets timing requirements for your application, as faster variants exist. Consult official AMD distributors for current availability status.

Complex Programmable Logic Devices Selection Notes

Select this model when high-speed performance (5ns delay) is required within the XC9500XL family. Choose PC44 packaging if space constraints fit the 44-pin PLCC form factor. Consider the -5 speed grade only if timing analysis confirms it is necessary, as slower grades offer lower cost. Verify that 72 macrocells provide sufficient logic resources for the design complexity.

Complex Programmable Logic Devices Part Context

The XC9500XL series represents an evolution of the original XC9500 CPLDs, offering higher density and improved performance while maintaining backward compatibility. This series bridges the gap between simple PALs/GALs and larger FPGAs. The XC9572 variant specifically provides 72 macrocells, making it suitable for moderately complex logic applications requiring non-volatile configuration and robust I/O capabilities.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other XC9500XL devices with equivalent or higher macrocell counts, such as XC9572-5PC44C or XC9572XL-5PC44C, provided pinouts match. For modern replacements, consider AMD LatticeMico8 or similar low-density CPLDs, though pin compatibility must be verified manually. No automatic pin-compatible upgrades exist outside the XC9500 family.
