CHAPTER
2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
The S1C63358 operating power voltage is as follows:
0.9 V to 3.6 V
Note: When a voltage within 0.9 V to 1.4 V is used as the operating power voltage, software control is
necessary (see Section 4.2).
When using the A/D converter with 0.9 V to 1.6 V power supply voltage, software control is
necessary.
The S1C63358 operates by applying a single power supply within the above range between VDD/AVDD
and VSS/AVSS. The S1C63358 itself generates the voltage necessary for all the internal circuits by the
built-in power supply circuits shown in Table 2.1.1.
