The supporting pin can reduce the influences from stresses on the function pins. Power Supply for Panel. This is the most positive voltage supply pin of the chip. It can be supplied externally or generated internally by using internal DC/DC voltage converter. Voltage Output High Level for COM Signal. This pin is the input pin for the voltage output high level for COM signal. A capacitor should be connected between this pin and VSS. Current Reference for Brightness Adjustment. This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current at 10uA. Host Data Input/Output Bus. These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. Read/Write Enable or Read. This pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low. Read/Write Select or Write. This pin is the Write (WR#) input. Data write operation is initiated when this pin is pulled low and CS# ispulled low Data/Command Control. This pin is Data/Command control pin. When the pin is pulled high, the input at D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0 will be transferred to the command register. For detail relationship to MCU interface signal, please refer to the Timing Characteristics Diagrams. Power Reset for Controller and Driver. This pin is reset signal input. When the pin is low, initialization of the chip executed. Chip Select. This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low. Power Supply for Logic circuit This is a voltage supply pin It must be connected to an external source. Ground This is a ground pin. It also acts as a reference for the logic pins, the OLED driving voltages, and the analogue circuits. It must be connected to external ground. Reserved Pin (Supporting Pin). The supporting pin can reduce the influences from stresses on the function pins. REV.
