Description
The ATV2500H/L is the most powerful programmable logic device available in a 40-
pin package. 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.
