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#) input. Data write operation is initiated when this pin is
pulled low and the CS# is pulled low.
When serial interface is selected, this pin must be connected to
VSS
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 interface 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.
Current Reference for Brightness Adjustment
This pin is segment current reference pin. A resistor should be
connected between this pin and VSS. Set the current lower than
10.0μA.
Voltage Output High Level for COM Signal
This pin is the input pin for the voltage output high level for
COM signals. A capacitor should be connected between this pin
and VSS.
Power Supply for OEL Panel
This is the most positive voltage supply pin of the chip. It must
be supplied externally.
Ground of Analogue Circuit
This is an analogue ground pin. It should be connected to VSS
externally.
Reserved Pin (Supporting Pin)
The supporting pin can reduce the influence from stress on the
function pins. This pin must be connected to external ground.
