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 (VCC = 3.3 V) and average link activity. Maximum current consumption is in maximum VCC 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.
