ATF22LV10CQZ

Description
The ATF22LV10CZ/CQZ is a high-performance CMOS
(electrically erasable) programmable logic device (PLD)
that utilizes Atmel’s proven electrically erasable Flash
memory technology and provides 25 ns speed with standby
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/CQZ provides a low-voltage and edgesensing “zero” power CMOS PLD solution with “zero”
standby power (5 µA typical). The ATF22LV10CZ/CQZ
powers down automatically to the zero power mode
through Atmel’s patented Input Transition Detection (ITD)
circuitry when the device is idle. The ATF22LV10CZ/CQZ
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 consumed by pull-up resistors. The “CQZ” combines
this low high-frequency I
of the “Q” design with the “Z”
CC
feature.
The ATF22LV10CZ/CQZ 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
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
ATF22LV10CZ/CQZ architecture.
The ATF22LV10CZ/CQZ has 12 inputs and 10 I/O macrocells. Each macrocell can be configured into one of four
output configurations: active high/low or registered/combinatorial. The universal architecture of the
ATF22LV10CZ/CQZ can be programmed to emulate most
24-pin PAL devices.

ATF22LV10C(Q)Z
Unused product terms are automatically disabled by the
compiler to decrease power consumption. A security fuse,
when programmed, protects the contents of the
ATF22LV10CZ/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.

Power-up Reset
The registers in the ATF22LV10CZ/CQZ are designed to
reset during power-up. At a point delayed slightly from V
crossing V
RST
The output state will depend on the polarity of the buffer.
This feature is critical for state machine initialization.
However, due to the asynchronous nature of reset and the
uncertainty of how V
following conditions are required:
1. The V
rise must be monotonic and start
CC
below 0.7V.
2. The clock must remain stable during T
3. After T
, all input and feedback setup times must
PR
be met before driving the clock pin high.
Preload of Register Outputs
The ATF22LV10CZ/CQZ’s registers are provided with circuitry to allow loading of each register with either a high or
a low. This feature will simplify testing since any state can
be forced into the registers to control test sequencing. A
JEDEC file with preload is generated when a source file
with vectors is compiled. Once downloaded, the JEDEC file
preload sequence will be done automatically by most of the
approved programmers after the programming.

Electronic Signature Word
There are 64 bits of programmable memory that are always
available to the user, even if the device is secured. These
bits can be used for user-specific data.
Security Fuse Usage
A single fuse is provided to prevent unauthorized copying
of the ATF22LV10CZ/CQZ fuse patterns. Once programmed, fuse verify and preload are inhibited. However,
the 64-bit User Signature remains accessible.
The security fuse should be programmed last, as its effect
is immediate.

Programming/erasing is performed using standard
PLD programmers. See CMOS PLD Programming

Input and I/O Pin Keepers
All ATF22LV10CZ/CQZ family members have internal input
and I/O pin-keeper circuits. Therefore, whenever inputs or
I/Os are not being driven externally, they will maintain their
last driven state. This ensures that all logic array inputs and
Input Diagram
device outputs are at known states. These are relatively
weak active circuits that can be easily overridden by TTLcompatible drivers (see input and I/O diagrams below).
