Description
The ATF22LV10CZ is a high performance CMOS (Electri-
cally Erasable) Programmable Logic Device (PLD) which
utilizes Atmel’s proven electrically erasable Flash mem-
ory technology and provides 25 ns speed with stand-by
current of 25 µA maximum. All speed ranges are specified
over the 3.0V to 5.5V range for industrial and commercial
temperature ranges.
The ATF22LV10CZ provides a low voltage and edge-
sensing “zero” power CMOS PLD solution with “zero”
standby power (5 µA typical). The ATF22LV10CZ powers
down automatically to the zero power mode through At-
mel’s patented Input Transition Detection (ITD) circuitry
when the device is idle. The ATF22LV10CZ is capable of
operating at supply voltages down to 3.0V. Pin “keeper”
circuits on input and output pins hold pins to their previous
logic levels when idle, which eliminate static power con-
sumed by pull-up resistors.
The ATF22LV10CZ macrocell incorporates a variable
product term architecture. Each output is allocated from 8
to 16 product terms which allows highly complex logic
functions to be realized. Two additional product terms are
included to provide synchronous reset and asynchronous
reset. These additional product terms are common to all
10 registers and are automatically cleared upon power up.
Register Preload simplifies testing. A Security Fuse pre-
vents unauthorized copying of programmed fuse patterns.

*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 any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Absolute Maximum Ratings*
Note: 1. Minimum voltage is -0.6V dc, which may undershoot
to -2.0V for pulses of less than 20 ns. Maximum out-
put pin voltage is Vcc + 0.75V dc, which may over-
shoot to 7.0V for pulses of less than 20 ns.
