CPLD (Complex Programmable Logic Device) is an integrated circuit with a wide range of programmable logic capabilities. It is a type of programmable logic device that can be used to implement complex digital logic functions. CPLDs are widely used in applications such as industrial control systems, robotics, data acquisition and embedded systems. Unlike FPGAs, CPLDs are not reconfigurable but are programmed once and can be used without the need for re-programming. CPLDs use a static RAM-based architecture that gives them the advantage of higher speed and lower power consumption when compared to FPGAs. CPLDs feature an array of programmable logic blocks with configurable interconnects that can be programmed to implement a variety of digital logic functions. The logic blocks can also be interconnected to form larger logic functions. In addition, some CPLD products feature embedded digital signal processors, analog and digital I/O, memories and clock-management circuitry, making them a versatile solution for many embedded applications.
