SPECIFICATIONS
Interface Pin Function
| No. | Symbol | Function |
|---|---|---|
| 1 | SDA | When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. |
| 2 | SCL | |
| 3 | DC | Data/Command Control This pin is Data/Command control pin.. When the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is pulled low, the data at SDIN will be transferred to the command register. |
| 4 | RST | This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) during normal operation. |
| 5 | CS | This pin is the chip select input. (active LOW). |
| 6 | VDD | 2.8 ~ 3.3V Power supply pin for core logic operation. |
| 7 | VIN | 4.8 ~ 5.2V Power supply pin for core logic operation. |
| 8 | GND | This is a ground pin. |
