| 1 | ESD-GND | It should be connected to ground. | |||||||||||||||
| 2 | C2N | C1P/C1N – Pin for charge pump capacitor; Connect to each other with a capacitor. C2P/C2N – Pin for charge pump capacitor; Connect to each other with a capacitor. |

| 4 | C1P | ||||||||||||||||
| 5 | C1N | ||||||||||||||||
| 6 | VBAT | 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 connected to VDD or kept float when the converter is not used. | |||||||||||||||
| 7 | VSS | This is a ground pin. | |||||||||||||||
| 8 | VDD | Power supply pin for core logic operation. | |||||||||||||||
| 9 | BS1 | These pins are MCU interface selection input. See the following table:
|
|||||||||||||||
| 10 | BS2 | ||||||||||||||||
| 11 | CS# | This pin is the chip select input. (active LOW). | |||||||||||||||
| 12 | RES# | This pin is reset signal input. When the pin is low, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation. | |||||||||||||||
| 13 | D/C# | This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDD), the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection. |
|||||||||||||||
| 14 | R/W# | This is read / write control input pin connecting to the MCU interface. When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH (i.e. connect to VDD) and write mode when LOW. When 8080 interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS. |
|||||||||||||||
| 15 | E/RD# | When interfacing to a 6800-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect to VDD) and the chip is selected. When connecting to an 8080-series microprocessor, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial or I2C interface is selected, this pin must be connected to VSS |
|||||||||||||||
| 16~23 | D0~D7 | These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. 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. |
|||||||||||||||
| 24 | IREF | This is segment output current reference pin. When external IREF is used, a resistor should be connected between this pin and VSS to maintain the IREF current at a maximum of 30uA.When internal IREF is used, this pin should be kept NC. |
|||||||||||||||
| 25 | VCOMH | The pin for COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. | |||||||||||||||
| 26 | 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. |
|||||||||||||||
| 27 | VLSS | This is an analog ground pin. It should be connected to VSS externally. | |||||||||||||||
| 28 | ESD GND | It should be connected to ground. |
