CHAPTER
2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
With a single external power supply (
) supplied to VDD through VSS, the S1C60N09 Series generates the
necessary internal voltages (<VS1> for oscillator and internal circuits and <VL1–VL3> for driving LCD)
with the internal power supply circuit.
Supply voltage: S1C60N09 ... 3.0 V S1C60L09 ... 1.5 V
The internal power supply circuit is configured according to the LCD drive voltage specification selected
by mask option. Figure 2.1.1 shows the configuration of the power supply circuit.
