When Not Using Internal Power Supply Step-Down Circuit

When the internal power supply step-down circuit is not used, connect the external power supply
to the V pin and V
CL
directly to the internal power supply. The permissible range for the power supply voltage is 3.0 V
to 3.6 V. Operation cannot be guaranteed if a voltage outside this range (less than 3.0 V or more
than 3.6 V) is input.
