XC9572-15PCG84C

Complex Programmable Logic Devices Overview

The XC9572-15PCG84C is a Complex Programmable Logic Device (CPLD) belonging to the AMD/Xilinx XC9500 family. It features 72 macrocells and supports up to 64 user I/O pins within an 84-pin Plastic Leaded Chip Carrier (PLCC) package. The device operates with a supply voltage range of 4.75V to 5.25V and offers a maximum propagation delay of 15ns. It utilizes In-System Programmability (ISP) via JTAG, allowing for non-volatile configuration without removal from the circuit board.

Complex Programmable Logic Devices Feature Summary

• 72 Macrocells with 1600 usable system gates
• In-System Programmability (ISP) via JTAG interface
• Non-volatile Flash technology for power-down retention
• Supports 64 user I/O pins in PLCC-84 package

Complex Programmable Logic Devices Applications

• Address decoding and bus interfacing
• Memory mapping and translation
• Simple state machine implementation
• Logic replacement for discrete TTL/CMOS circuits

Complex Programmable Logic Devices Procurement Notes

Verify the manufacturer origin, as the XC9500 family was originally developed by AMD before being acquired by Xilinx. Ensure the component matches the specific -15 speed grade and PCG84 package suffix. Check for RoHS compliance status, as older stock may not meet current environmental regulations. Confirm the device is new or properly tested surplus, as ISP capabilities can degrade if previously over-programmed.

Complex Programmable Logic Devices Selection Notes

Select this component when a moderate density CPLD with guaranteed non-volatility and ISP capability is required. The 15ns speed grade is suitable for medium-frequency digital logic applications. Compare against the XC9572XL series if lower voltage operation (3.3V) or higher performance is needed, noting that pinouts may differ. Ensure the design toolchain supports the legacy XC9500 architecture.

Complex Programmable Logic Devices Part Context

The XC9572 is part of the high-performance XC9500 CPLD family, which introduced Flash-based non-volatile technology to replace earlier EPROM-based devices. This family allows for unlimited reprogramming cycles and eliminates the need for UV erasure. The XC9572 specifically provides a balance of logic density and I/O count for general-purpose digital control tasks.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements are limited due to the proprietary architecture. Consider the XC9572-15PC84I for industrial temperature variants. For modern equivalents, evaluate Lattice MachXO or Microchip ATF1500 series, though these may require schematic redesign and do not offer identical functionality.
