NOTES:
1. Preferably, VIO should be 5 V ± 5% in any PCI environment (either 5 V or 3.3 V signaling). If 5 V is not
available in a 3.3 V signaling environment, 3.3 V ± 5% may be used instead. In CardBus, V_IO must be
identical to V_CC.
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 82551QM supports both the PCI and CardBus interface standards. In the PCI mode, it is five
volts tolerant and supports both 5 V and 3.3 V signaling environments.
