Description
The ATF22LV10C is a high performance CMOS (Electri-
cally Erasable) Programmable Logic Device (PLD) which
utilizes Atmel’s proven electrically erasable Flash memory
technology. Speeds down to 10 ns and power dissipation
as low as 10 µA are offered. All speed ranges are speci-
fied over the 3.0V to 5.5V range for industrial and commer-
cial temperature ranges.
The ATF22LV10C is capable of operating at supply volt-
ages down to 3.0V. When the power down pin is active,
the device is placed into a zero standby power down
mode. When the power down pin is not used or active, the
device operates in a full power low voltage mode. Pin
“keeper” circuits on input and output pins hold pins to their
previous logic levels when idle, which eliminate static
power consumed by pull-up resistors.
The ATF22LV10C provides a low voltage and user con-
trolled “zero” power CMOS PLD solution. A user-control-
led power down feature offers “zero” (5 µA typical)
standby power. This feature allows the user to manage
total system power to meet specific application require-
ments and enhance reliability, all without sacrificing
speed. (The ATF22LV10CZ provides edge-sensing “zero”
standby power (10 µA typical), as well as low voltage op-
eration. See the ATF22LV10CZ Data Sheet.)
The ATF22LV10C macrocell incorporates a variable prod-
uct term architecture. Each output is allocated from 8 to
16 product terms which allows highly complex logic func-
tions to be realized. Two additional product terms are in-
cluded 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.
Absolute Maximum Ratings*
*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.
