Description

The ATF16V8C is a high performance EECMOS Pro­grammable Logic Device that utilizes Atmel’s proven elec­trically erasable Flash memory technology. S peeds down
to 5 ns and a 100 µA pin-controlled power down mode op­tion 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 ATF16V8C 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 ATF16V8C can significantly reduce total system
power, thereby enhancing system reliability and reducing
power supply costs. When pin 4 is configured as the
power down control pin , supply current drops to less than
100 µA whenever the pin is high. If the power down fea­ture isn’t required for a particular application, pin 4 may be
used as a logic input. 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.

Power Up Reset

The ATF16V8C’s registers are designed to reset during
power up. At a point delayed slightly from V

, all registers will be reset to the low state. As a result,

the registered output state will always be high on power­up.

This feature is critical for state machine initialization. How­ever, due to the asynchronous nature of reset and the un­certainty of how V
lowing conditions are required:

1) The V

2) After reset occurs, all input and feedback setup times
must be met before driving the clock term high, and
