2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
With a single external power supply (
1) supplied to VDD through VSS, the S1C60N16 Series generates the
necessary internal voltage with the voltage regulator circuit (<VD1> for oscillators, <VC1> for LCD) and
the voltage booster circuit (<VC2 and VC3> for LCD).
1 Supply voltage: S1C60N16/60A16 .. 3 V, S1C60L16 .. 1.5 V
Figure 2.1.1 shows the power supply configuration.
The voltage <VD1> for the internal circuit is generated by the internal system voltage regulator.
The S1C60N16 Series generates <VC1> with the voltage regulator and <VC2, VC3> with the voltage
booster.
Notes: External loads cannot be driven by the output voltage of the voltage regulator and voltage
booster.
See Chapter 7, "Electrical Characteristics", for voltage values.

Fig. 2.1.1 Power supply configuration
The LCD system voltage regulator can be disabled by mask option. In this case, external elements can be
minimized because the external capacitors for the LCD system voltage regulator are not necessary.
However when the LCD system voltage regulator is not used, the display quality of the LCD panel, when
the supply voltage fluctuates (drops), is inferior to when the LCD system voltage regulator is used.
Figure 2.1.2 shows the external element configuration when the LCD system voltage regulator is not
used.
