2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
The S1C63406 operating power voltage is as follows:
Table 2.1.1 Operating power voltage
OSC1 clock
Max. 80 kHz
(crystal or CR)
OSC3 clock
Not use
Max. 700 kHz (CR)
Max. 2.2 MHz (CR)
Max. 4.2 MHz (crystal, ceramic or CR)
Operating power voltage
1.3 V–3.6 V
1.4 V–3.6 V
1.6 V–3.6 V
1.8 V–3.6 V
(When VC1 standard is selected)
The S1C63406 operates by applying a single power supply within the above range between VDD and VSS.
The S1C63406 itself generates the voltage necessary for all the internal circuits by the built-in power
supply circuits shown in Table 2.1.2.
