What is CPLD?

A Complex Programmable Logic Device (CPLD) is a programmable logic device with a complexity between that of PALs and FPGAs. A CPLD consists of multiple PAL-like logic blocks interconnected by a programmable interconnect matrix. CPLDs are typically used for implementing control logic, address decoding, and other general-purpose digital logic functions in a wide range of applications, including networking equipment, industrial control systems, and consumer electronics.
