I
Power supply for Power supply pin for the internal
internal step- step-down circuit. This pin must be
down circuit
connected to the system power
supply. This LSI does not operate
correctly if this pin is left open.
I
Ground for
Ground pin for the internal step-
internal step- down circuit. This pin must be
down circuit
connected to the system power
supply (0 V). This LSI does not
operate correctly if this pin is left
open.
I
Capacitor
Pin for connecting an external
connected pin for capacitor for the internal step-down
internal step- circuit. This pin should be connected
down circuit
to the VSS via the external capacitor
(place closer to this pin).
I
Ground for
Ground pin for the internal step-
internal step- down circuit used for stabilize
down circuit
internal step-down power supply.
This pin should be connected to the
VCL via the external capacitor (place
closer to this pin)
I
Power supply for Power supply pins for I/O pins. All
I/O circuits
the PVCC pins must be connected to
the system power supply. This LSI
does not operate correctly if there is
a pin left open.
I
Ground for I/O Ground pins for I/O pins. All the
circuits
PVSS pins must be connected to the
system power supply (0 V). This LSI
does not operate correctly if there is
a pin left open.
