Interface Definition
| PIN NO. | SYMBOL | TYPE | FUNCTION DESCRIPTIONS |
| 1 | NC(GND) | P | It should be connected to external ground. |
| 2 | C2P | C1P/C1N-Pin for charge pump capacitor. C2P/C2N-Pin for charge pump capacitor. Connect to each other with a capacitor. They must be floated when the Charge pump not use. | |
| 3 | C2N | ||
| 4 | C1P | I | |
| 5 | C1N | ||
| 6 | VBAT | P | Power supply for charge pump regulator circuit. It must be connected to external source when charge pump is used. It must be float when charge pump is not used. |
| 7 | VSS | P | Ground pin. It must be connected to external ground. |
| 8 | VDD | P | Power pin for logic circuit. It must be connected to external source. |
| 9 | BS1 | Interface selection pins. | |
| 10 | BS2 | ||
| 11 | CS# | I | Chip Select input pin. Active “L” |
| 12 | RES# | I | Hardware reset input pin. Active “L”. |
| 13 | D/C# | I | This is Data/Command control pin. When the pin is pulled HIGH, the data at D[7:0] is data. When the pin is pulled LOW, the data at D[7:0] is command. In I2C mode, this pin acts as SA0 for slave address section. When 3-wire serial interface is selected, this pin must be connected to VSS |
| 14 | R/W# | I | This is read/write control input pin. 8080: data write enable; 6800: read/write select pin. When serial or I2C interface is selected, this pin must be connected to VSS. |
| 15 | E/RD# | I | This is read/write control input pin. 8080: data read enable; 6800: read/write enable pin. When serial or I2C interface is selected, this pin must be connected to VSS. |
| 16 | D0 | I/O | These are 8-bit bi-directional data bus to be connected to microprocessor’s Data bus. When serial interface mode is selected, D2 should be kept NC, D1 will be the serial data input: SDIN, D0 will be the serial clock input: SCLK. When I2C mode is selected, D2, D1 should be tied together and serve as SDA and D0 is the serial clock input, SCL. |

| 24 | IREF | I | Current reference for brightness adjustment. This is segment output current reference pin. A resistor should be connected between this pin and VSS .Set the current at 12.5 uA maximum. |
| 25 | VCOMH | O | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
| 26 | VCC | P | Power supply for OLED driving voltage. A capacitor should be connected between this pin and VSS, when charge pump is used. It must be connected to external source when charge pump is not used. |
| 27 | VLSS | P | This is an analog ground pin. It should be connected to VSS externally. |
| 28 | NC(GND) | P | It should be connected to external ground. |
