taThe ATF2500C is the highest-density PLD available in a 44-pin package. With its fully
connected logic array and flexible macrocell structure, high gate utilization is easily
aobtainable. The ATF2500C is a high-performance CMOS (electrically-erasable) pro-
grammable logic device (PLD) that utilizes Atmel’s proven electrically-erasable
.Dtechnology.
