Interface Pin Description
| NO. | PIN NAME | I/O | Description |
| 1Â | GND | I | Power Ground |
| 2 | VDD | I | Power Supply for Analog, VDD=2.4V~3.3V. |
| 3 | IM2 | I | when IM1=0, IM2=0，8080-8bit;when IM1=1, IM2=1，4-line SPI serial I/F. |
| 4 | IM1 | I | |
| 5 | RESET | I | This signal will reset the device and it must be applied to properly initialize the chip. Signal is active low. |
| 6Â | CS | I | Chip selection pin; Low enable, High disable. |
| 7Â | D/C(SPI-SCL) | I | When connecting to an 8080-series microprocessor, this pin receives the data/command selection pin. This pin is used to be serial interface clock in 4-line serial interface. |
| 8Â | WR(SPI-RS)
（SPI-RS） |
I | When connecting to an 8080-series microprocessor, this pin receives the write signal. Display data/command selection pin in 4-line serial interface. |
| 9 | RD | I | When connecting to an 8080-series microprocessor, this pin receives the Read signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial interface is selected, this pin must be connected to Ground. |
| 10 | SDA | I | SPI interface input/output pin. The data is latched on the rising edge of the SCL signal. |
| 11-18 | D0-D7 | I | MCU parallel interface data bus. |
| 19 | NC | I | No Connect |
| 20 | LEDA | I | LED Anode |
