复杂可程序逻辑设备（英语：Complex Programmable Logic Device, CPLD），CPLD适合用来实现各种运算和组合逻辑（combinational logic）。一颗CPLD内等于包含了数颗的PAL（可程序数组逻辑），各PAL（逻辑区块）间的互接连接也可以进行程序性的规划、刻录，CPLD运用这种多合一（All-In-One）的集成作法，使其一颗就能实现数千个逻辑门，甚至数十万个逻辑门才能构成的电路。

A complex programmable logic device (CPLD) is a programmable logic device with complexity between that of PALs and FPGAs, and architectural features of both. The main building block of the CPLD is a macrocell, which contains logic implementing disjunctive normal form expressions and more specialized logic operations.
