PPoowweerr RReesseett ffoorr CCoonnttrroolllleerr aanndd DDrriivveerr
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.
CChhiipp SSeelleecctt
This pin is the chip select input. The chip is enabled for MCU communication only
when CS# is pulled low.
DDaattaa//CCoommmmaanndd CCoonnttrrooll
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.
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.
RReeaadd//WWrriittee EEnnaabbllee oorr RReeaadd
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 or I2C mode is selected, this pin must be connected to VSS.

RReeaadd//WWrriittee SSeelleecctt oorr WWrriittee
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#) 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.
HHoosstt DDaattaa IInnppuutt//OOuuttppuutt BBuuss
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.

The supporting pins can reduce the influences from stresses on the function pins.
These pins must be connected to external ground as the ESD protection circuit.

Note 1: All the above voltages are on the basis of “VSS = 0V”.
Note 2: When this module is used beyond the above absolute maximum ratings, permanent breakage of the
module may occur. Also, for normal operations, it is desirable to use this module under the
conditions according to Section 3. “Optics & Electrical Characteristics”. If this module is used
beyond these conditions, malfunctioning of the module can occur and the reliability of the module
may deteriorate.
Note 3: The defined temperature ranges do not include the polarizer. The maximum withstood
temperature of the polarizer should be 80C.
Note 4: VCC = 9.0V, Ta = 25°C, 50% Checkerboard.
Software configuration follows Section 4.4 Initialization.
End of lifetime is specified as 50% of initial brightness reached. The average operating lifetime at
room temperature is estimated by the accelerated operation at high temperature conditions.
