Description
The ATF16V8C is a high-performance EECMOS Program-
mable Logic Device that utilizes Atmel’s proven electrically-
erasable Flash memory technology. Speeds 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 soft-
ware, 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.

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-
