Stresses above the listed absolute maximum ratings may cause permanent damage to the 82559ER
device. This is a stress rating only and functional operations of the device at these or any other
conditions above 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.
10.2 DC Specifications
NOTES:
1. The VIO pin is the a voltage bias pin for the PCI interface. This pin should be connected to 5V ± 5% in a 5 volt
PCI system and 3.3 volts in a 3.3 volt PCI system. Be sure to install a 10K pull-up resistor. This resistor acts
as a current limit resistor in system where the VIO bias voltage maybe shutdown. In this cases the 82559ER
may consume additional current without a resistor.
2. Typical current consumption is in nominal operating conditions (V
CC
= 3.3 V) and average link activity.
Maximum current consumption is in maximum V
CC
and maximum link activity.
The 82559ER supports the PCI interface standards. The 82559ER’s PCI interface is five volts
tolerant and supports both 5 V and 3.3 V signaling environments.
