*NOTICE: Stresses beyond those listed under “Absolute Maxi-

mum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the

device at these or any other conditions beyond those indi-

cated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions

for extended periods may affect device reliability.

Absolute Maximum Ratings*

Note:

1. Minimum voltage is -0.6V dc, which may undershoot 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.

The ATF16V8CZ is a high performance EECMOS Pro-

grammable Logic Device which utilizes Atmel’s proven

electrically erasable Flash memory technology. Speeds

down to 12 ns and a 25

µA edge-sensing power down

mode are offered. All speed ranges are specified over the

full 5V

± 10% range for industrial temperature ranges; 5V

± 5% for commercial range 5-volt devices.

The ATF16V8CZ incorporates a superset of the generic

architectures, which allows direct replacement of the 16R8

family and most 20-pin combinatorial PLDs. Eight outputs

are each allocated eight product terms. Three different

modes of operation, configured automatically with soft-

ware, allow highly complex logic functions to be realized.

The ATF16V8CZ can significantly reduce total system

power, thereby enhancing system reliability and reducing

power supply costs. When all the inputs and internal

nodes are not switching, supply current drops to less than

25

µA. This automatic power down feature allows for

power savings in slow clock systems and asynchronous

applications. Also, the pin keeper circuits eliminate the

need for internal pull-up resistors along with their atten-

dant power consumption.
