Description
T h e A TF 1 6 V 8 C Z i s a h ig h - p e r f o rm a n c e E E C M OS
Programmable 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 applica-
tions. Also, the pin keeper circuits eliminate the need for
internal pull-up resistors along with their attendant power
consumption.
Absolute Maximum Ratings*
Temperature Under Bias.................................. -40°C to +85°C *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 V

+ 0.75V DC,
which may overshoot to 7.0V for pulses of less
than 20 ns.
