Description
The ATF16V8CZ is a high-perform ance EECMOS
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, wh ich allows di rect replac ement of th e 16R8
family and most 20-pin combinatorial PLDs. Ei ght outputs
are each allocated eight produc t terms. Three different

modes of operation, configured automatically with software, 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. Wh en al l the inpu ts an d inte rn al nodes
are not switchi ng, su pply cur rent dr ops to les s 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
Maximum Ratings” may cause permanent damage to the device . This is a s tress rating only and
functional operatio n of the dev ice at th ese or an y
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for exten ded periods may af fect 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
which may overshoot to 7.0V for pulses of less
than 20 ns.
