ATF2500C
The ATF2500C is organized around a single universal array. All pins and feedback terms are
always available to every macrocell. Each of the 38 logic pins are array inputs, as are the out-
puts of each flip-flop.
In the ATF2500C, four product terms are input to each sum term. Furthermore, each macrocell’s
three sum terms can be combined to provide up to 12 product terms per sum term with no per-
formance penalty. Each flip-flop is individually selectable to be either D- or T-type, providing
further logic compaction. Also, 24 of the flip-flops may be bypassed to provide internal combina-
torial feedback to the logic array.
Product terms provide individual clocks and asynchronous resets for each flip-flop. The flip-flops
may also be individually configured to have direct input pin clocking. Each output has its own
enable product term. Eight synchronous preset product terms serve local groups of either four or
eight flip-flops. Register preload functions are provided to simplify testing. All registers automati-
cally reset upon power-up.
