ATF750LVC

2

CMOS (electrically-erasable) complex programmable logic

device (CPLD) that utilizes Atmel’s proven electrically-eras-

able 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.

Absolute Maximum Ratings*

Temperature Under Bias.................................. -40°C to +85°C

*NOTICE:

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.

Note:

1.

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.
