Introduction to CPLDs

CPLDs ( Complex Programmable Logic Devices ) are an important element in the field of embedded design. They are an excellent tool for bridging the gap between the basic logic and microprocessor technologies, allowing circuit designers to create complex logic designs without having to use multiple integrated circuits. CPLDs are based on technology known as \'flash\' memory, allowing users to store programming information within the device. This programming information is similar to the assembly language used for microprocessors, and provides a much more efficient means of designing circuitry compared to traditional integrated circuit technology.

XC95288-15HQ208C Application Field and Working Principle

The XC95288 CPLD family are high-density CPLDs used in numerous embedded design applications. The XC95288-15HQ208C device is an ideal choice for designs with very limited space. The XC95288-15HQ208C offers a maximum of 15,000 usable programmable logic cells and 16 I/O blocks which can be configured as either logic ports or general-purpose I/O. The low power consumption and small package size results in a very suitable design for projects requiring high volume control with low power needs.

The XC95288-15HQ208C is a Field-Programmable Gate Array (FPGA). It is programmed with a special configuration file (written in Verilog or VHDL languages) and its internal gates are configured to the specified design. The device is programmed with a special programming ‘flash loader’ device which is attached to the development board. In addition to the configuration file, the FPGA also requires an \'initialising program\' to enable it to work correctly.

The XC95288-15HQ208C allows for the implementation of a wide range of digital logic functions, such as arithmetical operations, logic comparisons and memory access. In addition, it can be used to create control pathways, as on/off control signals, pulse width modulators, pulse-code modulation encoders and decoders. XC95288-15HQ208C can also be used to create serial communications links between microprocessor and external devices, as well as to interface directly with a variety of hardware devices.

Conclusion

XC95288-15HQ208C is an ideal device for embedded design projects that require complex logic and a high degree of flexibility. Its extremely low power requirements, combined with its small form factor and large capacity, make it a perfect fit for many embedded design applications. Its ability to easily interface with both microprocessor-based systems and external devices makes it a great choice for projects that require high volume control over a large array of digital inputs and outputs. CPLDs such as the XC95288-15HQ208C provide the ideal platform for creating complex logic circuitry without taking up valuable board space or consuming large amounts of power.
