PIN DESCRIPTIONS
D/
C
This pin is Data/ Command control pin. When the pin is pulled high, the data at D
7
-D
0
is treated as display data.
When the pin is pulled low, the data at D
7
-D
0
will be transferred to the command register.
R/
W
(
WR
)
This pin is microprocessor interface input. When interfacing to a 6800-series microprocessor, this pin will be used
as R/W signal input. Read mode will be carried out when this pin is pulled high and write mode when low.
When interfacing to a 8080-microprocessor, this pin will be the
WR
input. Data write operation is initiated when
this pin is pulled low and the chip is selected.
This pin must be fixed to high or low in serial mode.
DVDD & AVDD
Digital and Analog Power supply pin.
DVSS & AVSS
Ground.
E(
RD
)
This pin is microprocessor interface input. When interfacing to a 6800-series microprocessor, this pin will be used
as the enable signal, E. Read/ Write operation is initiated when this pin is pulled high and the chip is selected.
When interfacing to a 8080-microprocessor, this pin receives the
RD
signal. Data read operation is initiated when
this pin is pulled low and the chip is selected.
This pin must be fixed to high or low in serial mode.
CS
This pin is the chip select input.
D
7
-D
0
These pins are the 8-bit bi-directional data bus to be connected to the microprocessor in parallel interface mode.
In 8-bit bus mode, D
7
is the MSB while D
0
is the LSB. In 4-bit bus mode, it is needed to transfer 4-bit data (through
D
7
-D
4
) by two times. The high order bits (for 8-bit mode D
7
-D
4
) are written before the low order bits (for 8-bit mode
D
3
-D
0
) in write transaction and low order bits (8-bit mode D
3
-D
0
) are read before the high order bits (8-bit mode D
7
-
D
4
) in read transaction. The D
3
-D
0
pins must be fixed to high or low in 4-bit bus mode. After resets, SSD1801
considers first 4-bit data from MPU as the high order bits.
When serial mode is selected, D
7
is the serial data input (SDA) and D
6
is the serial clock input (SCK). D5-D0 must
be fixed to high or low in serial mode

VL6 is the most positive LCD driving voltage. It can be supplied externally or generated by the internal regulator. It is
recommended to add a capacitor between VL6 and Vss for external regulator.
