ATV750B
2
Each of the ATV750B’s 22 logic pi ns can be used as an
input. Ten of these can be used as inputs, outputs or bidirectional I/O pins. Each flip-flop is individually configurable as either D- or T-type. Each fl ip-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 avai lable. A va riable format is used to assign between four to eight product terms
per sum term. There are two sum terms per outpu t, providing added flexibility. Much more logic can be replaced by
this device than by any other 24-pin PLD. Wi th 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 output has i ts o wn ena ble p roduct term. One produc t
term provides a com mon synchronous preset for a ll flipflops. Registe r prel oad fun ctions a re prov ided t o simp lify

The ATV750BL is a low power device with speeds as fast
as 15 ns. The ATV750BL pro vides the optimu m low power
PLD solution, with full CMOS output levels. This device significantly reduces total system power, thereby allowing battery-powered operation.
