Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of
those given in the operations sections of this data sheet. Exposure to absolute maximum ratings for extended periods
can adversely affect device reliability.
The ORCA Series FPGAs include circuitry designed to protect the chips from damaging substrate injection currents
and prevent accumulations of static charge. Nevertheless, conventional precautions should be observed during stor-
age, handling, and use to avoid exposure to excessive electrical stress.
Recommended Operating Conditions
Notes:
During powerup and powerdown sequencing, V
DD
is allowed to be at a higher voltage level than V
DD
5 for up to 100 ms.
During powerup sequencing of OR2TxxA devices V
DD
should reach 1.0 V before voltage applied to V
DD
5 can be greater than the voltage applied
to V
DD.
The maximum recommended junction temperature (T
J
) during operation is 125 °C.
