ATV750B

2

Each of the ATV750B’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 config-

urable 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. A variable for-

mat is used to assign between four to eight product terms

per sum term. There are two sum terms per output, provid-

ing added flexibility. 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 individu-

ally configured to have direct input pin controlled clocking.

Each output 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.

The ATV750BL is a low power device with speeds as fast

as 15 ns. The ATV750BL provides the optimum low power

PLD solution, with full CMOS output levels. This device sig-

nificantly reduces total system power, thereby allowing bat-

tery-powered operation.
