Description
Several low power options allow selection of the best so-
lution for various types of power-limited applications. Each
of these options significantly reduces total system power
and enhances system reliability.
The ATF22V10C is a high performance CMOS (Elec-
trically Erasable) Programmable Logic Device (PLD)
which utilizes Atmel’s proven electrically erasable
Flash memory technology. Speeds down to 5 ns and
power dissipation as low as 100 µA are offered. All
speed ranges are specified over the full 5V ± 10%
range for industrial temperature ranges, and 5V ± 5%
for commercial temperature ranges.
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.

Power Up Reset
The registers in the ATF22V10Cs are designed to reset
1. The V rise must be monotonic, and starts below
CC
during power up. At a point delayed slightly from V
0.7V,
CC
crossing V
, all registers will be reset to the low state.
RST
2. After reset occurs, all input and feedback setup times
must be met before driving the clock pin high, and
The output state will depend on the polarity of the output
buffer.
3. The clock must remain stable during t
.
PR
This feature is critical for state machine initialization. How-
ever, due to the asynchronous nature of reset and the un-
certainty of how V actually rises in the system, the fol-
CC
lowing conditions are required:

Preload of Registered Outputs
Security Fuse Usage
The ATF22V10C’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.
A single fuse is provided to prevent unauthorized copying
of the ATF22V10C 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
Electronic Signature Word
Programming/erasing is performed using standard PLD
programmers. See CMOS PLD Programming Hardware &
Software Support for information on software/program-
ming.
There are 64 bits of programmable memory that are al-
ways available to the user, even if the device is secured.
These bits can be used for user-specific data.
Input and I/O Pin Keeper Circuits
The ATF16V8C contains internal input and I/O pin keeper
circuits. These circuits allow each ATF16V8C pin to hold
its previous value even when it is not being driven by an
external source or by the device’s output buffer. This helps
insure that all logic array inputs are at known, valid logic
levels. This reduces system power by preventing pins
from floating to indeterminate levels. By using pin keeper
circuits rather than pull-up resistors, there is no DC current
required to hold the pins in either logic state (high or low).
These pin keeper circuits are implemented as weak feed-
back inverters, as shown in the Input Diagram below.
These keeper circuits can easily be overdriven by stand-
ard TTL- or CMOS-compatible drivers. The typical over-
drive current required is 40 µA.
