The ACT™ 1 Series of field programmable gate arrays(FPGAs) offers a variety of package, speed, and applicationcombinations. Devices are implemented in silicon gate,1-micron two-level metal CMOS, and they employ Actel’sPLICE® antifuse technology. The unique architecture offersgate array flexibility, high performance, and instantturnaround through user programming. Device utilization istypically 95 to 100 percent of available logic modules.ACT 1 devices also provide system designers with uniqueon-chip diagnostic probe capabilities, allowing convenienttesting and debugging. Additional features include an on-chipclock driver with a hardwired distribution network. Thenetwork provides efficient clock distribution with minimumskew.
