| 5 | VBAT | Power Supply for DC/DC Converter Circuit This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be float when the converter is not used. |
||||||||
| 6 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. When charge pump is enabled, a capacitor should be connected between this pin and VSS. |
||||||||
| 7 | VSS | Ground of Logic Circuit This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground. |
||||||||
| 8 | VDD | Power Supply for Logic This is a voltage supply pin. It must be connected to external source. |
||||||||
| 9 | BS0 | Communicating Protocol Select These pins are MCU interface selection input. See the following table:
|
||||||||
| 10 | BS1 | |||||||||
| 11 | CS# | Chip Select This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low. |
||||||||
| 12 | RES# | Power Reset for Controller and Driver This pin is reset signal input. When the pin is low, initialization of the chip is executed. |
||||||||
| 13 | D/C# | In I2C mode, this pin acts as SA0 for slave address selection. When 3-wire serial interface is selected, this pin must be connected to VSS. |
||||||||
| 14~16 | D0~D2 | When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN. When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL. |
||||||||
| 17 | IREF | Current Reference for Brightness Adjustment This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 30uA. |
||||||||
| 18 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
||||||||
| 19 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. When charge pump is enabled, a capacitor should be connected between this pin and VSS. |
||||||||
| 20 | VLSS | Ground of Analog Circuit This is an analog ground pin. It should be connected to VSS externally. |
