3POWER SOURCE
3.1 Power Supply System
The S1C6S460 operating power voltage is as follows:
2.2–5.5 V (Min. 1.8 V, when OSC3 oscillation circuit is not used)
The S1C6S460 operates when a single power supply within the above range is applied between VDD and
VSS. Even if the voltage is not within the above range necessary for the internal circuits, the IC itself can
generate the following built-in power circuits.
Circuit
Power supply circuit
Output voltage
Oscillation circuit and internal circuits
Regulated voltage circuit
VS1
LCD driver
LCD system voltage circuit
VL1–VL5
Notes: VL3 is used only when the driving voltage of the LCD system will be supplied externally (1/5
bias); when using the internal LCD system voltage circuit (1/4 bias), it should be shorted with
VL2.
See "14 Electrical Characteristics" for voltage values.
