WEN025664D-CTP is a 5.5-inch COF OLED display module with integrated PCB, frame, and capacitive touch panel. It features a 256x64 resolution and is driven by the SSD1322 controller IC. The module supports 6800/8080 8-bit parallel and 3-/4-wire SPI interfaces, operates at 3V, uses a 1/64 duty cycle, and provides 4-bit grayscale.
The integrated capacitive touch panel (CTP) is based on the GT911 controller with I2C interface, supporting single-touch input. The touch panel features a standard glare surface and is suitable for user interface interaction in embedded applications.
This module includes an integrated PCB that simplifies system integration by allowing direct wire connection without additional carrier board design. Multiple connection options such as PIN, FFC, CN, and FPC are supported. Four mounting holes are provided for easier mechanical installation.
The operating temperature range is -20°C to +70°C, and the storage temperature range is -30°C to +80°C.
Additional OLED panel options include:
This 5.5-inch OLED module is suitable for applications such as POS systems, vending machines, medical devices, and industrial control systems.

| 4 | D/C# | I | Data/Command Control 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. |
||||||||||
| 5 | R/W# (WR#) |
I | 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 mode is selected, this pin must be connected to VSS. |
||||||||||
| 6 | E/RD# | I | 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 mode is selected, this pin must be connected to VSS. |
