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.

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 20ns.
Maximum output pin voltage is V

+ 0.75V DC,
which may overshoot to 7.0V for pulses of less
than 20ns.

Power-up Reset
The registers in the Atmel
®
ATF22V10B are designed to reset during power-up. At a point delayed slightly from
V
CC
crossing V
RST
, all registers will be reset to the low state. The output state will depend on the polarity of the out-
put buffer.
This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the
uncertainty of how V
CC
actually rises in the system, the following conditions are required:
1. The V
CC
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 t
