Description
The ATF22LV10C is a high performance CMOS (Electrically 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 ar e spec ified over the 3.0V to 5.5V range for industrial and commercial temperature ranges.
The ATF22LV10C provides a low voltage and user controlled “zero” power CMOS PLD solution. A us er-controlled power down feature offers “zero” (5 µA typical)
standby power. This feature allows the user to manage
total system power to meet specific application requirements and enha nce reliability, all without sacrificing
speed. (The ATF22LV10CZ provides edge-sensing “zero”
standby power (10 µA typical), as well as low voltage operation. See the ATF22LV10CZ Data Sheet.)
Absolute Maximum Ratings*
The ATF22LV10C is capable of operating at supply voltages 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 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 prevents 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 an y ot he r con ditions beyond those indicated in the oper ational 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 undershoot
to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is Vcc + 0.75V dc, which may overshoot to 7.0V for pulses of less than 20 ns.

Functional Logic Diagram Description
The Functional Logic Diagram describes the
ATF22LV10C architecture.
The ATF22LV10C has 12 inputs and 10 I/O macrocells.
Each macrocell can be configured into one of four output
configurations: active high/low, registered/combinatorial
output. The universal architecture of the ATF22LV10C
can be programmed to emulate most 24-pin PAL devices.

Unused product terms are automatically disabled by the
compiler to decrease power consumption. A Security
Fuse, when programmed, protects the contents of the
ATF22LV10C. Eight bytes (64 fuses) of User Signature
are accessible to the user for purposes such as storing
project nam e, part number, revision or date. The User
Signature is accessible regardless of the state of the Security Fuse.
