2POWER SUPPLY AND INITIAL RESET
2.1 Power Supply
The S1C6P466 operating power voltage is as follows:
Table 2.1.1 Operating power voltage
Operating mode
MCU normal operation mode
PROM programming mode
Operating power voltage
2.7 V–5.5 V
5.0 V
±10%
The S1C6P466 operates by applying a single power supply within the above range between VDD/VDDF
and VSS. The S1C6P466 generates the voltage necessary for all the internal circuits by the built-in power
supply circuits shown in Table 2.1.2. Supply the same voltage level as VDD to the VDDF terminal from
outside the IC.

Notes: Do not drive external loads with the output voltage from the internal power supply circuits.
The internal LCD system voltage circuit (1/4 bias) is always used in the S1C6P466, connect
between VC3 and VC2 terminals.
See Chapter 9, "Electrical Characteristics", for voltage values and drive capability.
