Section 18 Power Supply Circuit
18.2
When the internal power supply step-down circuit is not used, connect the external power supply
to the V
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.
