SPECIFICATIONS

Interface Pin Function

No. Symbol Function
1 SDA The I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.
2 SCL
3 DC In I2C mode, this pin acts as SA0 for slave address selection.
When 3-wire serial interface is selected, this pin must be connected to VSS.
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.
