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.

10.2DC Specifications

Table 15. General DC Specifications

Symbol	Parameter	Condition	Min	Typical	Max	Units	Notes
VCC	Supply Voltage		3.0	3.3	3.5	V
VIO	Periphery Clamp	PCI	4.75	5.0	5.25	V	1
	Voltage
ICC	Power Supply			125	195	mA	2

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.
