Description
The Atmel® ATF22V10B is a high-performance CMOS (electrically erasable) programmable logic device (PLD)
which utilizes the Atmel proven electrically erasable Flash memory technology. Speeds down to 7.5ns and power
dissipation as low as 10mA are offered. All speed ranges are specified over the full 5V  10% range for military and
industrial temperature ranges, and 5V  5% for commercial temperature ranges.
Several low-power options allow selection of the best solution for various types of power-limited applications. Each
of these options significantly reduces total system power and enhances system reliability.

Power-up Reset
The registers in the Atmel® ATF22V10B are designed to reset during power-up. At a point delayed slightly from
VCC crossing VRST, all registers will be reset to the low state. The output state will depend on the polarity of the output buffer.
This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the
uncertainty of how VCC actually rises in the system, the following conditions are required:
1. The VCC rise must be monotonic
2. After reset occurs, all input and feedback setup times must be met before driving the clock pin high
3. The clock must remain stable during tPR

Preload of Registered Outputs
The Atmel® ATF22V10B 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.

Security Fuse Usage
A single fuse is provided to prevent unauthorized copying of the ATF22V10B 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.
12.
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.
13.
Programming/Erasing
Programming/erasing is performed using standard PLD programmers. See CMOS PLD Programming
Hardware and Software Support for information on software/programming.

Input and I/O Pull-ups
All Atmel® ATF22V10B family members have internal input and I/O pull-up resistors. Therefore, whenever inputs or
I/Os are not being driven externally, they will float to VCC. This ensures that all logic array inputs are at known
states. These are relatively weak active pull-ups that can easily be overdriven by TTL-compatible drivers (see input
and I/O diagrams below).
