utilizes Atmel’s proven electrically-erasable Flash memory
technology. Speeds down to 7.5 ns and power dissipation
as low as 10 mA are offered. All speed ranges are specified
over the full 5V
± 10% range for military and industrial

ture 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.
*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.

Power-up Reset
Military
The registers in the ATF22V10Bs are designed to reset
during power-up. At a point delayed slightly from V
ing V
, all registers will be reset to the low state. The
RST
cross-
CC
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 V
actually rises in the system, the
CC
following conditions are required:
1. The V
rise must be monotonic,
CC
2. After reset occurs, all input and feedback setup times
must be met before driving the clock pin high, and
3. The clock must remain stable during t
PR
.
Preload of Registered Outputs
The ATF22V10B’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.

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.
