2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
The S1C63466 operating power voltage is as follows:

Not use
Use
Operating power voltage
1.8 V–6.4 V
2.2 V–6.4 V
The S1C63466 operates by applying a single power supply within the above range between VDD and VSS.
The S1C63466 itself generates the voltage necessary for all the internal circuits by the built-in power
supply circuits shown in Table 2.1.2.

Output voltage
VD1
VC1–VC5
Note: Do not drive external loads with the output voltage from the internal power supply circuits.
VC3 should be used only when the LCD drive voltage is supplied externally (1/5 bias); when
using the internal LCD system voltage circuit (1/4 bias), short between VC3 and VC2 terminals.
See Chapter 7, "Electrical Characteristics", for voltage values and drive capability.
