WEX025664D ist ein 5,5-Zoll-OLED-Display mit einer Auflösung von 256x64 Pixeln und COF-Aufbau (Chip on Film). Das grafische OLED-Display verwendet den Controller-IC SSD1322 und unterstützt eine 4-Bit-Graustufendarstellung mit 16 Graustufen. Für die Anbindung stehen parallele 6800/8080-Schnittstellen mit 8 Bit sowie SPI mit 3 oder 4 Leitungen zur Verfügung.
Das COF-OLED-Display hat Außenabmessungen von 146,0 × 45,0 × 2,01 mm und eine aktive Anzeigefläche von 135,65 × 33,89 mm. Da OLEDs selbstleuchtend sind, ist keine separate Hintergrundbeleuchtung erforderlich. Die 16 Graustufen ermöglichen die Darstellung von Texten, Symbolen und grafischen Elementen mit unterschiedlichen Helligkeitsstufen. Der Betriebstemperaturbereich liegt zwischen -40°C und +80°C.
WEX025664D kommt für industrielle Steuergeräte, Messgeräte, Kommunikationssysteme und medizinische Geräte infrage, bei denen ein grafisches OLED-Display im breiten Format benötigt wird.

| 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. | ||||||||||
