Description
The ACT™ 1 Series of field programmable gate arrays
(FPGAs) offers a variety of package, speed, and application
combinations. Devices 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 devices also provide system designers with unique
on-chip diagnostic probe capabilities, allowing convenient
testing and debugging. Additional features 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 include plastic
and ceramic J-leaded chip carriers, ceramic
