2.3 Power Supply for I/O Interface (V
The V
voltage is used for interfacing with external I/O signals. For the output interface of the S1C33L03, the
DDE
V
voltage is used as high level and the V

Normally, supply the same voltage level as V

The following voltage is enabled for V

Notes: • The S1C33L03 has 4 V
them.
• When an external clock is input to the OSC1 or OSC3 pin, the clock signal level must be V
• The interface voltage level of the DSIO, P10, P11, P12, P13 and P14 pins is V
2.4 Power Supply for Analog Circuits (AV
The analog power supply pin (AV
circuits do not affect the analog circuit (A/D converter). The AV
