+5V
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).

CORE_VDD
This pin provides power to the core circuitry of
the CL-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 con-
nected to the 3.3-volt supply even if there is no
intention of operating other interfaces on the
device at less than 5 volts.
