It must be connected to external source. **Ground of Logic Circuit** 3 VSS This is a ground pin. It also acts as a reference for the logic pins. It must be connected to external ground. P **Power Supply for OEL Panel** 23 VCC This is the most positive voltage supply pin of the chip. It must be supplied externally. **Ground of Analog Circuit** 2 VLSS This is an analog ground pin. It should be connected to VSS externally. ~~—~~ **Dirver** Pin Number Symbol Type Function **Current reference for Brightness Adjustment** 21 IREF I This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current at 10μA maximum. **Voltage Output High Level for COM Signal** 22 VCOMH O This pin is the input pin for the voltage output high level for COM signals.

This pin is reset signal input. When the pin is low, initialization of the chip
is executed. Keep this pin pull high during normal operation.||| |8|CS#||**Chip Select**
This pin is the chip select input. The chip is enabled for MCU
communication only when CS# is pulled low.||| |10|D/C#||**Data/Command Control**
This pin is Data/Command control pin. When the pin is pulled high, the
input at D7~D0 will be interpreted as display data. When the pin is pulled
low, the input at D7~D0 will be transferred to the command register.
When the pin is pulled high and serial interface mode is selected, the data
at SDIN will be interpreted 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. For detail relationship to MCU
interface signals, please refer to the Timing Characteristics Diagrams.||| |12|E/RD#||**Read/Write Enable or Read**
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.
When serial mode is selected, this pin must be connected to VSS.||| |11|R/W#||**Read/Write Select or Write**
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 to “Low” for write
mode.
When 80XX interface mode is selected, this pin will be the Write (WR#)||| Page 5 of 11 |input. Data write operation is initiated when this pin is pulled low and the
CS# is pulled low.
When serial or I2C mode is selected, this pin must be connected to VSS.

**Host Data Input/Output Bus**
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 selected, D2, D1 should be tired together and serve as
SDAOUT, SDAIN in application and D0 is the serial clock input, SCL.
Unused pins must be connected to VSS except for D2 in serial mode.
