DESCRIPTION 
The Pin for charge pump capacitor; Connect to each other with a capacitor. 
Power supply for charge pump regulator circuit. 
No Connection. 
Ground. 
Power supply pin for core logic operation. 
No Connection. 
Table 5-1 
Chip Select, active LOW. 
This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is 
executed. 
Keep this pin HIGH (i.e. connect to VDD) during normal operation. 
This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDD), 
the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be 
transferred to the command register. 
In I2C mode, this pin acts as SA0 for slave address selection. 
This is read / write control input pin connecting to the MCU interface. 
When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write 
(R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH 
(i.e. connect to VDD) and write mode when LOW. 
When 8080 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 chip is selected. 
When serial or I2C interface is selected, this pin must be connected to VSS. 
When interfacing to a 6800-series microprocessor, this pin will be used as the Enable 
(E) signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect 
to VDD) and the chip is selected. 
When connecting to an 8080-series microprocessor, this pin receives the Read (RD#) 
signal. Read operation is initiated when this pin is pulled LOW and the chip is 
selected. 
When serial or I2C interface is selected, this pin must be connected to VSS. 
These are 8-bit bi-directional data bus to be connected to the microprocessor’s data 
bus.   
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 
will be the serial data input: SDIN and D2 should be kept NC. 
When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, 
SDAin in application and D0 is the serial clock input, SCL. 
Segment output current reference pin 
Common signal deselected voltage level. Connected a capacitor to VSS. 
Power supply for panel driving voltage. 
No Connection.

Note (1): All of the voltages are on the basis of “VSS = 0V”. 
Note (2): Permanent breakage of module may occur if the module is used beyond the maximum rating. The 
module can be normal operated under the conditions according to Section 8 “Electrical 
Characteristics”. Malfunctioning of the module may occur and the reliability of the module may 
deteriorate if the module is used beyond the conditions.
