Chips designed for a particular limited product or application are called application-specific integrated circuits (ASICs), and usually fall into one of five groups of semicustom components: programmable logic devices (PLDs), erasable programmable logic devices (EPLDs), field programmable gate arrays (FPGAs), gate arrays, and standard cells. When compared to other circuit realizations, ASICs generally require less components. This leads to smaller, faster designs which consume less power.
