Complex Programmable Logic Devices, commonly referred to as CPLDs, are a class of programmable logic device (PLD) which offer enhanced capabilities over their simpler counterparts, the Programmable Logic Arrays (PLA) and Programmable Array Logic (PAL) devices. The Xilinx XC9536XL-7VQG64C is classified as a CPLD, with its application field and working principle discussed in this article.

Application Field of XC9536XL-7VQG64C

Being a CPLD, Google\'s XC9536XL-7VQG64C is designed with more sophisticated logic capabilities than devices from the other two PLD classes. This CPLD is ideal for application scenarios requiring more intricate logical operations, particularly rapid control of two or more digital circuits. Typical applications for the XC9536XL-7VQG64C include programmable logic controllers, computer sound cards, home and office entertainment systems, consumer electronics, embedded systems, and other automated control and interfacing applications. It can be used in these applications to program logical operations, timing events, coordination of multiple tasks, and even interfacing between processor and storage components.

Working Principle of XC9536XL-7VQG64C

The Xilinx XC9536XL-7VQG64C CPLD is based on Xilinx\'s 6-output macrocell logic technology. This means that, while the product configuration is predisposed to suit certain applications, the user is free to configure each macrocell as required. On top of this, the device offers 10 programmable system I/O pins for various features such as high-speed access ports, address bus decode, timing circuits, reset and clock control.

Internally, the Xilinx XC9536XL-7VQG64C is equipped with a 4Kbit configuration block containing an array of configurable logic blocks and I/O registers. This configuration block serves as the interface between the logic structured RAM and the logic circuit, allowing the user to modify the logical operations of the device as needs change. With the in-built serial Flash ROM and a built-in ROM controller, configuration data is loaded into the configuration block. The device then processes the configuration data and enables or disables the function and I/O as specified.

In addition, the XC9536XL-7VQG64C utilizes the ‘Functional Multiplier’ architecture to provide a 4-input programmable function unit which includes combination functions and a 4-level priority multiplexer tree. This device also uses an advanced ‘Density Enhancement’ transistor technology which provides fast switching speeds, low power with little internal loading, and high function density for custom logic devices.

In summary, the Xilinx XC9536XL-7VQG64C is an advanced Complex Programmable Logic Device (CPLD) designed to provide the user with more sophisticated logic capabilities. It is ideal for application scenarios requiring more intricate logical operations, particularly rapid control of two or more digital circuits. This device supports the user with a 4Kbit configuration block, a 4-input programmable function for combination functions and a 4-level priority multiplexer tree, and an advanced ‘Density Enhancement’ transistor architecture.
