Description

(Continued)

The ATF16V8CZ i s a high performance EECMOS Pro­grammable Logic Device which utilizes A tmel’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 soft­ware, allow highly complex logic functions to be realized.

The ATF16V 8CZ 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 atten­dant power consumption.

*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 an y ot he r con ditions beyond those indi­cated in the oper ational 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 undershoot to -

2.0V for pulses of less than 20 ns. Maximum output pin
voltage is Vcc + 0.75 V dc, whic h may overshoot to 7. 0V
for pulses of le ss than 20 ns.
