Pin Name
Power supply pins for the controller block.
Normally, V
When only the CPU operates (when the
75-kHz/32.768-kHz oscillator is used), it can
operate at
V
In the backup state (when the CKSTP
instruction is executed), current dissipation
decreases (10 µ A or below), allowing the power
supply voltage to be reduced to 1.0 V.
Raising the voltage on MVDD pin from 0 V to
1.8 V or higher triggers a system reset, causing
the program to start from address 0 (power-on
reset).
(Note) At power-on reset operation, allow 1 ms
