CHAPTER
2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
The S1C63567 operating power voltage is as follows:
Supply voltage VDD = 2.2 V to 5.5 V
The S1C63567 operates by applying a single power supply within the above range between VDD and VSS.
The S1C63567 itself generates the voltage necessary for all the internal circuits by the built-in power
supply circuits shown in Table 2.1.1.

2.1.1 Voltage <VD1> for oscillation circuit and internal circuits
VD1 is a voltage for the oscillation circuit and the internal logic circuits, and is generated by the oscillation
system voltage regulator for stabilizing the oscillation. The VD1 voltage is fixed at 2.1 V, so it is not
necessary to control by software.
2.1.2 Voltage <VC1–VC5> for LCD driving
VC1, VC23, VC4 and VC5 are the LCD (1/4 bias) drive voltages generated by the LCD system voltage
circuit. These four output voltages can only be supplied to the externally expanded LCD driver.
The LCD system voltage circuit generates VC23 with the voltage regulator built-in, and generates three
other voltages by boosting or reducing the voltage of VC23. Table 2.1.2.1 shows the VC1, VC23, VC4 and VC5
voltage values and boost/reduce status.

Note: The LCD drive voltage can be adjusted by the software (see Section 4.7.5). Values in the above
table are typical values.
Refer to Section 4.7, "LCD Driver", for control of the LCD drive voltage.
