|**Pin**|**Symbol**|**Description**||||**Remarks**|
|1|NC|No Connection. Must connect to external Ground.|||||
|2|VSS|**Ground of Logic Circuit.**<br>Ground pin, also acts as a reference for logic pins. Must<br>connect to external ground.|||||
|3|VCC|**Power Supply for OLED Panel.**<br>Most positive voltage supply pin of the chip. They must be<br>connected to external source.|||||
|4|VCOMH|**Voltage Output High Level for COM Signal.**<br>Input pin for the voltage output high level for COM signals. A<br>tantalum capacitor should be connected between this pin and<br>VSS.|||||
|5|VLSS|**Ground of Analogue Circuit.**<br>These are the analogue ground pins. They should be<br>connected to VSS externally.|||||
|6~13|D7~D0|**Host Data Input / Output Bus.**<br>8-bit bi-directional data bus pins to be connected to the<br>microprocessor’s data bus. When serial mode is selected, D1<br>will be the serial data input SDIN and D0 will be the serial<br>clock input SCLK. Unused pins must be connected to VSS<br>except for D2 in serial mode|||||
|14|E/RD#|**Read / Write Enable or Read.**<br>MCU interface input. When interfacing to a 6800<br>microprocessor, this pin will be used as the Enable (E)<br>signal. Read/write operation is initiated when this pin is<br>pulled high and the CS# is pulled low.<br>When connecting to an 8080 microprocessor, this pin<br>receives the Read (RD#) signal. Data read operation is<br>initiated when this pin is pulled low and CS# is pulled low.<br>When serial mode is selected, this pin must be connected to<br>VSS.|||||
|15|R/W#|**Read / Write Select or Write.**<br>MCU interface input. When interfacing to a 6800 series<br>microprocessor, this pin will be used as Read/Write (R/W#)<br>selection input. Pull this pin to “High” for read mode and pull<br>it to “Low” for write mode.<br>When 8080 interface mode is selected, this pin will be the<br>Write (WR#) input. Data write operation is initiated when this<br>pin is pulled low and the CS# is pulled low. When serial<br>mode is selected, this pin must be connected to VSS.|||||
|16|BS0|**Communicating Protocol Select.**<br>MCU interface selection input. See below table:<br>3-Wire SPI: BS0=1 BS1=0<br>4-Wire SPI: BS0=0 BS1=0<br>6800 Parallel: BS0=1 BS1=1<br>8080 Parallel: BS0=0 BS1=1|||||
|17|BS1||||||
|18|D/C#|**Data / Command Control.**<br>When the pin is pulled high, the input at D7~D0 is treated as<br>display data. When the pin is pulled low, the input at D7~D0<br>will be transferred to the command register.|||||
|19|CS#|**Chip Select.**<br>Chip Select Input. The chip is enabled for MCU<br>communication only when CS# is pulled low.|||||
|20|RES#|**Power Reset for Controller and Driver.**<br>Reset signal input. When the pin is low, initialization of the<br>chip is executed.|||||
|21|FR|**Frame Frequency Triggering Signal.**|||||

|||This pin will send out a signal that could be used to identify<br>the driver status. Nothing should be connected to this pin. It<br>should be left open individually.||
|---|---|---|---|
|22|IREF|**Current Reference for Brightness Adjustment.**<br>Segment current reference pin. A resistor should be<br>connected between this pin and VSS. Set the current lower<br>than 10uA.||
|23|NC|No Connection. Reserved for compatible and flexible design.||
|24|VDDIO|**Power Supply for I/O Pin**<br>Power supply pin of I/O buffer. It should be connected to<br>VDD or external source. All I/O signal should have VIH<br>reference to VDDIO. When I/O signal pins (BS0~BS1,<br>D0~D7, control signals…) pull high, they should be<br>connected to VDDIO.||
|25|VDD|**Power Supply for Core Logic Circuit.**<br>Voltage supply pin. It can be supplied externally (within the<br>range of 2.4~2.6V) or regulated internally from VCI. A<br>capacitor should be connected between this pin & VSS under<br>all circumstances.||
|26|VCI|**Power Supply for Operation.**<br>This is a voltage supply pin. It must be connected to external<br>source & always be equal to or higher than VDD & VDDIO.||
|27|VSL|**Voltage Output Low Level for SEG Signal.**<br>This is segment voltage reference pin.<br>When external VSL is not used, this pin should be left open.<br>When external VSL is used, this pin should connect with<br>resistor and diode to ground.||
|28|VLSS|**Ground of Analogue Circuit.**<br>These are the analogue ground pins. They should be<br>connected to VSS externally.||
|29|VCC|**Power Supply for OLED Panel.**<br>Most positive voltage supply pin of the chip. They must be<br>connected to external source.||
|30|NC|No Connection. Must connect to external Ground.||
