2 Symbol Definition
VCC: Power supply for panel driving voltage.
VSS: This is ground pin.
VDD: Power supply for core logic operation.
VDDIO: Power supply for interface logic level.
BS0~BS2: MUC bus interface selection pin (BS0 pulled LOW in internal).
CS: This pin is chip select input (active LOW).
RES: This pin is reset signal input (active LOW).
D/C: This is DATA/COMMAND control pin. When it is Pulled HIGH, the data at D[0~7] is treated as
data. When it is pulled LOW, the data at D[0~7] will be transferred to the command register. In I2C
mode, this pin acts as SA0 for slave address select.
R/W: This is read/write control input pin connecting to the MCU interface. When interface to a 6800-
series microprocessor, Read mode will be carried out when this pin is pulled HIGH and write mode
when low. When interface to an 8080-microprocessor, this pin when be the data Write input. When
serial interface is selected, this pin must be connected to Vss.
E/RD: When interface to a 6800-series microprocessor, this pin will be used as the Enable (E) signal.
When interface to an 8080-microprocessor, this pin receives the Read (RD#)signal.
D0~D7:These are 8-bit bi-directional data bus to be connected to the microprocessors data bus.
When serial interface mode is selected, D0 (SCLK) will be the serial clock input, D1 (SDIN) will be the
serial data input and D2 should be left opened. When I2C mode is selected, D1 (SDAin) AND D2
(SDAout) should be tied together, D0 (SCL) is the I2Cclock input
IREF: This is segment output current reference pin.
VCOMH: This pin for COM signal deselected level voltage.

5 Power down and Power Up sequence
To protect the OLED panel and extend the panel life time the driver IC power up/down
routine should include a delay period between high voltage and low voltage power sources
during turn on/off. So that the panel has enough time to charge up or discharge before/ after
operation.
