SPECIFICATIONS

Interface Pin Function

No. Symbol Function
1 GND Ground pin.
2 VCC Power supply pin for core logic operation.
3 D0 The serial clock input
4 D1 The serial data input
5 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.
6 D/C# This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D1 will be interpreted as data.
When the pin is pulled LOW, the data at D1 will be transferred to a command register.
7 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).
