High-speed UV Erasable Programmable Logic Device

Atmel Corporation 

Each of the ATV750B(L) 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. A variable format is used to assign between four

to eight product terms per sum term. There are two sum terms per output, providing 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 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.

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

significantly reduces total system power, thereby allowing battery-powered operation.

*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 VCC + 0.75V

DC which may overshoot to +7.0V for pulses of

less than 20 ns.
