Flash memory technology. Speeds down to 12 ns with zero
standby power dissipation 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 ATF22V10CZ/CQZ provides a low voltage
and edge-sensing “zero” power CMOS PLD solution with
“zero” standby power (5 µA typical). The
ATF22V10CZ/CQZ provides a “zero” power CMOS PLD
solution with 5V operating voltages, powering down auto­matically to the zero power-mode through Atmel’s patented
Input Transition Detection (ITD) circuitry when the device is
idle, offering “zero” (25 µA worst case) standby power. This
feature allows the user to manage total system power to

“CQZ” combines the low high-frequency I

design with the “Z” feature.
The ATF22V10CZ/CQZ incorporates a superset of the

generic architectures, which allows direct replacement of
the 22V10 family and most 24-pin combinatorial PLDs. Ten
outputs are each allocated 8 to 16 product terms. Three
different modes of operation, configured automatically
with software, allow highly complex logic functions to be
realized.

*NOTICE: Stresses beyond those listed under “Absolute

Maximum 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 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
which may overshoot to 7.0V for pulses of less
than 20 ns.

Functional Logic Diagram Description

The Functional Logic Diagram describes the
ATF22V10CZ/CQZ architecture.

The ATF22V10CZ/CQZ 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
ATF22V10CZ/CQZ 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
ATF22V10CZ/CQZ. Eight bytes (64 fuses) of User Signa­ture are accessible to the user for purposes such as storing
project name, part number, revision or date. The User Sig­nature is accessible regardless of the state of the security
fuse.
