WEN025664A-CTP is a 2.8-inch monochrome graphic COF OLED display module with a projected capacitive touch panel, featuring a resolution of 256x64 dots. It is built with the SSD1322 IC and supports 6800/8080 8-bit parallel and 3-/4-wire SPI interfaces. The module outline measures 85.0 × 39.8 mm, with an active area of 69.1 × 17.26 mm. The integrated PCAP uses the FT6336U IC, supports an I2C interface, and provides 1-point touch.
This OLED module operates with a 3V power supply and a 1/64 duty driving method. It supports grayscale display and offers a high contrast ratio of 10,000:1. The operating temperature range is -20°C to +70°C, and the storage temperature range is -30°C to +80°C.
WEN025664A-CTP is designed with a metal frame and an onboard PCB, and includes four mounting holes to support easier mechanical installation. With interface settings and VDD circuitry integrated on the PCB, the module can be connected to the application system directly by wires, helping simplify integration and reduce additional board design work.
The WEN025664A-CTP series is also available in a version without a touch panel. For the non-touch option, please refer to the WEN025664A series.

| 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. |
