Table 48. Flash/EEPROM Interface DC Specifications
The 82551ER supports PCI interface standards. In the PCI mode, it is five volts tolerant and
supports both 5 V and 3.3 V signaling environments.
NOTES:
1. These values are only applicable in 3.3 V signaling environments. Outside of this limit the input buffer must
2. Input leakage currents include high-Z output leakage for all bidirectional buffers with tristate outputs.
3. Signals without pull-up resistors have 3 mA low output current; and signals requiring pull-up resistors, 6 mA.
4. This value is characterized but not tested.
5. This input leakage current is the maximum allowable leakage into the PME# open drain driver when power is
1. This value is characterized but not tested.
