These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus.
When serial mode is selected, D
SCK.
V
Power supply pin.
Ground reference of Vref.
Ground reference of analog circuitry.
Ground reference of logic circuitry.
Reference voltage input for internal DC-DC converter. The voltage of generated V
the multiple factor (2X, 3X, 4X or 5X) times V
Note: Voltage at this input pin must be larger than or equal to V
This is the most positive voltage supply pin of the chip. It can be supplied externally or
generated by the internal regulator.
LCD driving voltages. They can be supplied externally or generated by the internal bias divider.
They have the following relationship:
These pins provide the row driving signal COM0 - COM63 to the LCD panel. See Figure 5 or
Figure 7 about the COM signal mapping in different multiplex ratio N.
This pin is the special icons line COM signal output.
