Increased product terms, sum terms, and flip-flops translate into many more usable gates. High gate utilization is easily obtainable. The ATV2500H/L is organized around a global bus. All pin and feedback terms are always available to every logic cell. Each of the 38 logic pins and their complements are array inputs, as well as the true and false outputs of each of the 48 flip-flops.
