| 5 | 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. |
| 6 | NC | No connection. |
| 7 | VSS | This is a ground pin. |
| 8 | VDD | Power supply pin for core logic operation. |
| 9 | 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. |
| 10 | SCL | The serial clock input |
| 11 | SDA | The serial data input/output |
| 12 | 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. |
| 13 | VCOMH | The pin for COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
| 14 | VCC | This is the most positive voltage supply pin. When charge pump is enabled, a capacitor should be connected between this pin and VSS. |
