Square OLED Display 9664
Winstar released a Hot Bar FPC version for WEO009664B model. This is a 1.1 inch passive matrix square OLED display module which is made of 96x64 dots with Hot Bar FPC. The WEO009664B-Hotbar version is also built in with SSD1327 IC, it supports 6800/8080 8-bit parallel, I2C, and 4-Wire SPI interface, 3V power supply, 1/64 duty cycle and 16-bit gray scale. This 1.1" WEO009664B-Hotbar model can be regarded as an alternative of 1.1” TAB WEX009664A/B model which had been EOL in 2017. These models have similar Active Area size and having same diagonal size of 1.1 inch.
The OLED display which is ultra thin and no need of backlight; it’s lightweight and low power consumption. It is suitable for portable device, personal care appliance, health device, meter device, etc. The released emitting color for this item is available in yellow. WEO009664B module can be operating at temperatures from -40℃ to 80℃; its storage temperatures range from -40℃ to 85℃.

Interface Pin Function
|1||VSS||Ground pin. It must be connected to external ground.|
|2||VCC||Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source.|
|3||VCOMH||COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS. No external power supply is allowed to connect to this pin.
|4||VCI||Low voltage power supply and power supply for interface logic level. It should match with the MCU interface voltage level and must be connected to external source.
VCI must always set to be equivalent to or higher than VDD.
|5||VDD||Power supply pin for core logic operation.|
|6||BS1||MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2, BS1 and BS0 are pin select.
Bus Interface selection
|8||VSS||Ground pin. It must be connected to external ground.|
|9||IREF||This pin is the segment output current reference pin|
|10||CS#||This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
|11||RES#||This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.
|12||D/C#||This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.
When 3-wire serial interface is selected, this pin must be connected to VSS.
|13||R/W#||This pin is read / write control input pin connecting to the MCU interface.
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW.
When 8080 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 chip is selected.
|14||E||This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal.
Read/write operation is initiated when this pin is pulled HIGH and the chip is
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.
|15||D0||These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SDIN and D2 should be kept NC.
When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.
|23||VCC||Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source.|
