| 1 | ESD_GND | This pin should be connected to GND. | ||||||
| 2 | VPP | OLED panel power supply. Connect to capacitor. It could be supplied externally. This is the most positive voltage supply. |
||||||
| 3 | VCOMH | This is a pin for the voltage output high level for common signals. A capacitor should be connected between this pin and VSS. |
||||||
| 4 | SEGH | This is a segment pre-charge voltage. A capacitor can be connected between this pin and GND if necessary. When external capacitor is not used, this pin should be kept NC. |
||||||
| 5 | VSL | Discharge voltage level pad. This pad should be connected to resistor and diode externally. |
||||||
| 6 | VSS | Ground for logic and analog. This pin should be connected to GND externally. | ||||||
| 7 | VDD | Power supply for logic. | ||||||
| 8 | RES | This is a reset signal input pin. When RES is set to “L”, the settings are initialized. The reset operation is performed by the RES signal level. This pin internal pull high. |
||||||
| 9 | A0/SA0 | This is the Data/Command control pin that determines whether the data bits are data or a command. In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. |
||||||
| 10 | CS | This pin is the chip select input. When CS = “L”, then the chip select becomes active, and data/command I/O is enabled. | ||||||
| 11 | SCL | The serial clock input. | ||||||
| 12 | SI | The serial data input. | ||||||
| 13 | IM1 | MCU bus interface selection pins.
|
||||||
| 14 | IREF | This is a segment current reference pin. A resistor should be connected between this pin and GND. |
||||||
| 15 | DVDD | This pin is for regulator circuit. A capacitor should be connected between this pin and GND if necessary. When external capacitor Is not used, this pin should be kept NC |
||||||
| 16 | ESD_GND | This pin should be connected to GND. |
