| 3 | NC | No connection |
| 4~11 | D0~D7 | Data bus. |
| 12 | CS | This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW). |
| 13 | NC | No connection |
| 14 | /RES | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
| 15 | R/W | This pin is read / write control input pin connecting to the MCU interface. When 8080 interface mode is selected, this pin is pulled LOW and the chip is selected |
| 16 | D/C | This pin is Data/Command control pin connecting to the MCU. |
| 17 | E | This pin is MCU interface input. When 8080 interface mode is selected, this pin is pulled LOW and the chip is selected |
| 18 | NC | No connection |
| 19 | DISP | Display off when it's pulled low; Display on when it's pulled high. |
