delays guarantee fast in-system performance. The
ATF750LVC is a high-performance CMOS (electrically-
erasable) complex programmable logic device (CPLD) that
utilizes Atmel’s proven electrically-erasable technology.
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 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. 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 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.
*NOTICE:
Note:
1.
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
Minimum voltage is -0.6V DC, which may under-
shoot to -2.0V for pulses of less than 20 ns.
Maximum output pin voltage is V
which may overshoot to 4.6V for pulses of less
than 20 ns.
