VDDO
3.3 V
Dedicated power supply for oscillator
GNDO
3.3 V
Dedicated GND for oscillator
VDDAD
3.3 V
Dedicated power supply for the A/D and D/A converters.
The voltage applied to this pin becomes the maximum voltage value for the A/D and
D/A converters’ interface signals.
GNDAD
3.3 V
Dedicated GND for the A/D and D/A converters.
The voltage applied to this pin becomes the minimum voltage value for the A/D and
D/A converters’ interface signals.
VDDTP
3.3 V
Dedicated power supply for touch panel interface
GNDTP
3.3 V
Dedicated GND for touch panel interface
Caution
The V
R
4181A includes two power supply systems, a 2.5 V system and a 3.3 V system. When
applying a voltage, be sure to apply it to the 3.3 V power supply system first. Apply voltage to
the 2.5 V power supply system according to the status of the MPOWER pin.
