El WEX025664D es una pantalla OLED de 5,5 pulgadas con una resolución de 256x64 píxeles y estructura COF (Chip on Film). Esta pantalla OLED gráfica incorpora el controlador SSD1322 y admite una escala de grises de 4 bits (16 niveles). Dispone de interfaces paralelas 6800/8080 de 8 bits y SPI de 3 o 4 hilos.
La pantalla OLED COF tiene unas dimensiones de 146,0 × 45,0 × 2,01 mm y un área activa de 135,65 × 33,89 mm. Al tratarse de una tecnología autoemisiva, OLED no requiere retroiluminación. Los 16 niveles de gris permiten mostrar textos, iconos y elementos gráficos con diferentes niveles de intensidad luminosa. Su rango de temperatura de funcionamiento es de -40°C a +80°C.
El WEX025664D puede utilizarse en equipos de control industrial, instrumentos de medición, equipos de comunicación y dispositivos médicos que requieran una pantalla OLED gráfica de formato horizontal.

| 1 | N.C. | The N.C. pin between function pins are reserved for compatible and flexible design. | ||||||||||
| 2 | VSS | Ground. | ||||||||||
| 3 | VCC | Power supply for panel driving voltage. This is also the most positive power voltage supply pin. |
||||||||||
| 4 | VCOMH | COM signal deselected voltage level. A capacitor should be connected between this pin and VSS. |
||||||||||
| 5 | VLSS | Analog system ground pin. | ||||||||||
| 6~13 | D7~D0 | These pins are bi-directional data bus connecting to the MCU data bus. Unused pins are recommended to tie LOW. (Except for D2 pin in SPI mode) |
||||||||||
| 14 | E/RD# | This pin is MCU interface input. When interfacing to a 6800-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 chip is selected. When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial interface is selected, this pin E(RD#) must be connected to VSS. |
||||||||||
| 15 | R/W# | This pin is read / write control input pin connecting to the MCU interface. When interfacing to a 6800-series microprocessor, 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. When serial interface is selected, this pin R/W (WR#) must be connected to VSS. |
||||||||||
| 16 | BS0 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table.
(1) 0 is connected to VSS (2) 1 is connected to VDDIO |

| 17 | BS1 | |||||||||||
| 18 | D/C# | This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the content at D[7:0] will be interpreted as data. When the pin is pulled LOW, the content at D[7:0] will be interpreted as command. |
||||||||||
| 19 | 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. | ||||||||||
