CPLD - Complex Programmable Logic Devices

CPLDs are large-scale logic devices with up to thousands of programmable logic elements, non-volatile memory, and I/O block on one chip. Connections between the logic elements on these semiconductor chips are customized by the user with software tools. CPLD architecture has a predictable timing performance and speed, offers a range of logic capabilities, and is often employed in portable, battery-operated applications. FPGAs are denser and more complex than CPLDs and are used to implement larger or more complex designs.
