Fonction

No connection

VPP

This is the most positive voltage supply pad of the chip.
It should be supplied externally.

VSEGM

This is a segment pre-charge voltage.
A capacitor can be connected between this pad and VSS if necessary. When external capacitor Is not used, this pin should be kept NC.

VCOMH

This is a pad for the voltage output high level for common signals.
A capacitor should be connected between this pad and VSS.

VSL

Discharge voltage level pad.
This pad should be connected to resistor and diode externally.

No connection

IREF

This is a segment current reference pad.
A resistor should be connected between this pad and VSS.

VPP

This is the most positive voltage supply pad of the chip.
It should be supplied externally.

No connection

VSS

Ground for logic and analog. This pad should be connected to GND externally.

VCL

This is a common voltage reference pad.
This pad should be connected to VSS externally.

VDD

Power supply for logic and input/output

IM0

These are the MPU interface mode select pads.

VDD

Power supply for logic and input/output

CSB

This pad is the chip select input. When CSB = "L ", then the chip select becomes active, and data command I/O is enabled. When in I2C interface, this pin is not used, so it must be connected to “L”.

RESB

This is a reset signal input pad. When RESB is set to "L", the settings are initialized. The reset operation is performed by the RESB signal level. This pin internal pull high.

This is the Data/Command control pad that determines whether the data bits are data or a command.
A0 = "H": the inputs at D0 to D7 are treated as display data.
A0 = "L": the inputs at D0 to D7 are transferred to the command registers.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. When in 3-wire interface, this pin is not used, so it must be connected to "L".

WRB

This is a MPU interface input pad.
When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU WR signal. The signals on the data bus are latched at the rising edge of the WR signal.
When connected to a 6800 Series MPU: This is the read/write control signal input terminal. When R/W = "H": Read.
When R/W = "L": Write.
When in 3-wire.4-wire & I2C interface, this pin is not used, so it must be connected to “L”.

RDB

This is a MPU interface input pad.
When connected to an 8080 series MPU, it is active LOW. This pad is connected to the RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is "L".
When connected to a 6800 series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU.
When in 3-wire.4-wire & I2C interface, this pin is not used, so it must be connected to "L" .

This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
When the serial interface(SPI) and I2C is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). At this time, D2 to D7 are set to high impedance. D7~D2 is recommended to connect the VDD or GND. It is also allowed to leave D7~D2 unconnected.

No connection

VPP

This is the most positive voltage supply pad of the chip.
It should be supplied externally.
