Description and Introduction

XC9572: 5V ISP CPLD Family The XC9572 is a CPLD (Complex Programmable Logic Device) manufactured by Xilinx. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Technology:** 5V in-system programmable (ISP) CPLD  
- **Macrocells:** 72  
- **Usable Gates:** 1,600  
- **Maximum I/O Pins:** 72  
- **Operating Voltage:** 5V ±10%  
- **Propagation Delay:** 7.5 ns (pin-to-pin)  
- **Package Options:**  
  - PLCC (84-pin)  
  - VQFP (100-pin)  
  - TQFP (100-pin)  
  - PC84 (84-pin)  

### **Descriptions:**  
- The XC9572 is part of the XC9500 family, designed for high-performance, low-power applications.  
- It supports in-system programming (ISP) via JTAG (IEEE 1149.1).  
- Features FastFLASH™ technology for reprogrammability.  
- Suitable for glue logic, bus interfacing, and state machine applications.  

### **Features:**  
- **High-Speed Performance:** 7.5 ns pin-to-pin delay.  
- **ISP Capability:** Reprogrammable via JTAG interface.  
- **Flexible I/O:** 5V tolerant inputs, 24 mA drive capability.  
- **Low Power Consumption:** Standby current as low as 50 µA.  
- **Security:** Programmable security bit to prevent readback.  
- **Architecture:** 5-input function blocks with 36 to 72 macrocells.  

This device is commonly used in digital logic designs requiring fast reprogrammability and moderate complexity.
