A '''complex programmable logic device''' ('''CPLD''') is a [[programmable logic device]] with complexity between that of [[Programmable Array Logic|PAL]]s and [[Field-programmable gate array|FPGA]]s, and architectural features of both. The main building block of the CPLD is a [[Macrocell array|macrocell]], which contains logic implementing [[disjunctive normal form]] expressions and more specialized logic operations.
