Pin Name
Table 5. Power and Ground Pins
Table 6. Pin Usage Summary
This pin is connected to the system’s 5-volt
power supply. In systems where 5 volts is not
available, this pin can be connected to the
system’s 3.3-volt supply (but 5-volt-only PC
Cards will not be supported).
This pin provides power to the core circuitry of
the PD67XX. It can be connected to either a
3.3- or 5-volt power supply, independent of the
operating voltage of other interfaces. For power
conservation on a system with a 3.3-volt supply
available, this pin should be connected to the
3.3-volt supply even if there is no intention of
operating other interfaces on the device at less
than 5 volts.
All ground pins should be connected to system
ground.
Table 6
Power-On Configuration Summary
On the rising edge of PWRGOOD, the PD67XX latches the configuration pin SPKR_OUT*/
C_SEL to determine which sockets are addressed by this device. A ‘1’ on the SPKR_OUT*/
C_SEL pin will cause the device to address Socket 0 (and Socket 1 for the PD6722). A ‘0’ on this
pin will cause the device to address Socket 2 (and Socket 3 for the PD6722).
