These pins must be connected to external ground. Ground of Analog Circuit This is an analog ground pin. It should be connected to VSS externally Ground of OEL System 3 VSS This is a ground pin. It also acts as a reference for the logic pins, the OEL driving voltages, and the analog circuits. It must be connected to external ground. 4 N.C. 5 VDD No Connection Power Supply for Logic Circuit 6 BS1 Communicating Protocol Select 7 BS2 8 CS# 9 RES# This is a voltage supply pin. It must be connected to external source. These pins are MCU interface selection input. See the following table: Chip Select This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low. Power Reset for Controller and Driver This pin is reset signal input. When the pin is low, initialization of the chip is executed. Data/Command Control 10 D/C# 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 signals, please refer to the Timing Characteristics Diagrams. 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. In I2C mode, this pin acts as SA0 for slave address selection. Read/Write Select or Write 11 R/W# This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Pull this pin to “High” for read mode and pull it “Low” for write mode. When 80XX interface mode is selected, this pin will be the Write (WR#) input. Data write operation is initiated when this pin is pulled low and the CS# is pulled low. Read/Write Enable or Read 12 E/RD# This pin is MCU interface input. When interfacing to a 68XX-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled high and the CS# is pulled low. When connecting to an 80XX-microprocessor, this pin receives the Read (RD#) signal. Data read operation is initiated when this pin is pulled low and CS# is pulled low. Host Data Input/Output Bus 13~20 D0~D7 Product No. These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. When I2C mode is DD-12832BE-1A REV.

Current Reference for Brightness Adjustment 21 IREF This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 10uA 22 VCOMH This pin is the input pin for the voltage output high level for COM signals. A capacitor should be connected between this pin and VSS. 23 VCC 24 N.C.(GND) Product No. Voltage Output High Level for COM signal Power Supply for OEL Panel This is the most positive voltage supply pin of the chip. It must be supplied externally. Reserved Pin (Supporting Pin) The supporting pins can reduce the influences from stresses on the function pins. These pins must be connected to external ground.
