3. Pin Configurations

ATF750LVC
Each of the ATF750LVC’s 22 logic pins can be used as an input. Ten of these can be used as
inputs, outputs or bi-directional I/O pins. Each flip-flop is individually configurable as either
D- or T-type. Each flip-flop output is fed back into the array independently. This allows burying
of all the sum terms and flip-flops.
There are 171 total product terms available. There are two sum terms per output, providing
added flexibility. A variable format is used to assign between four to eight product terms per
sum term. Much more logic can be replaced by this device than by any other 24-pin PLD. With
20 sum terms and flip-flops, complex state machines are easily implemented with logic to
spare.
Product terms provide individual clocks and asynchronous resets for each flip-flop. Each flip-
flop may also be individually configured to have direct input pin controlled clocking. Each out-
put has its own enable product term. One product term provides a common synchronous
preset for all flip-flops. Register preload functions are provided to simplify testing. All registers
automatically reset upon power-up.
