The ACT™ 1 Series of field programmable gate arrays (FPGAs) offers a variety of package, speed, and application combinations. ACT™ 1 Series are implemented in silicon gate, 1-micron two-level metal CMOS, and they employ Actel's PLICE® antifuse technology. The unique architecture offers gate array flexibility, high performance, and instant turnaround through user programming. Device utilization is typically 95 to 100 percent of available logic modules.

ACT™ 1 Series also provide system designers with unique on-chip diagnostic probe capabilities, allowing convenient testing and debugging. Additional features of ACT™ 1 Series include an on-chip clock driver with a hardwired distribution network. The network provides efficient clock distribution with minimum skew.

The user-definable I/Os are capable of driving at both TTL and CMOS drive levels. Available packages of ACT™ 1 Series include plastic and ceramic J-leaded chip carriers, ceramic and plastic quad flatpacks, and ceramic pin grid array.

A security fuse of ACT™ 1 Series may be programmed to disable all further programming and to protect the design from being copied or reverse engineered.
