series introduction

# Introduction to the XC9572 - 15PC84C Product Series

## 1. Overview
The XC9572 - 15PC84C belongs to the Xilinx XC9500 family of Complex Programmable Logic Devices (CPLDs). These devices are renowned for their versatility, high - performance, and reliability, making them a popular choice in a wide range of electronic applications. The XC9572 - 15PC84C, in particular, offers a unique combination of features that cater to the needs of various design requirements.

## 2. Key Specifications

### 2.1 Logic Capacity
The "72" in the XC9572 - 15PC84C indicates its logic capacity. It has 72 macrocells, which are the building blocks of the CPLD. These macrocells can be configured to implement a variety of logic functions, such as combinational logic (e.g., AND, OR, NOT gates) and sequential logic (e.g., flip - flops). This allows designers to create complex digital circuits, from simple control units to more elaborate state machines.

### 2.2 Speed Grade
The "15" represents the speed grade of the device. A lower speed grade number generally indicates a faster device. In the case of the XC9572 - 15PC84C, it is designed to operate at relatively high speeds, enabling it to handle high - frequency signals and perform rapid logic operations. This makes it suitable for applications where real - time processing is crucial, such as in communication systems and high - speed data acquisition.

### 2.3 Package Type
The "PC84" refers to the package type. It comes in a 84 - pin Plastic Quad Flat Pack (PQFP). This package offers a compact form factor while providing a sufficient number of pins for connecting to external components. The PQFP package is also well - suited for surface - mount technology (SMT) assembly, which is widely used in modern printed circuit board (PCB) manufacturing processes.

### 2.4 Temperature Range
The "C" at the end of the part number typically indicates the commercial temperature range. The XC9572 - 15PC84C is designed to operate reliably within the temperature range commonly found in commercial environments, usually from 0°C to 70°C. This makes it suitable for a variety of consumer and industrial applications where the operating temperature is within this range.

## 3. Features

### 3.1 In - System Programmability (ISP)
One of the significant features of the XC9572 - 15PC84C is its in - system programmability. This means that the device can be programmed or reprogrammed while it is installed on the PCB. Designers can make changes to the logic configuration of the CPLD without having to remove it from the board, which simplifies the development process and allows for easy updates and modifications.

### 3.2 Non - Volatile Memory
The XC9572 - 15PC84C uses non - volatile memory to store its configuration. Once programmed, the device retains its logic settings even when the power is turned off. This eliminates the need for external configuration memory chips in many applications, reducing the overall component count and cost of the system.

### 3.3 Flexible I/O Configuration
The device offers a flexible I/O configuration. It has a number of input/output pins that can be individually configured as inputs, outputs, or bidirectional ports. This flexibility allows designers to interface the CPLD with a wide variety of external devices, such as sensors, actuators, and other integrated circuits.

### 3.4 JTAG Support
The XC957
