Function
Power supply pins
Connect all Vcc pins to the system
power supply. The LSI does not
operate if any Vcc pins are open.
Ground pin
Connect all Vss pins to the system
power supply (0V). The LSI does not
operate if any pins are open.
External capacitance pins for internal
step-down power supply
Connect these pins to Vss via a 0.47
µF capacitor (should be placed close
to the pins).
Ground pin for the on-chip PLL
oscillator
Connected to a crystal resonator.
An external clock signal may also be
input to the EXTAL pin.
Connected to a crystal resonator.
Supplies the system clock to external
devices. The SH7136 does not have
this pin.
