Description
The WEN025664A-CTP series is a 2.8-inch monochrome graphic COF OLED display featuring a capacitive touch panel with a resolution of 256x64 dots. It is equipped with the SSD1322 IC and supports multiple interfaces, including 6800/8080 8-bit and 3/4-wire SPI interfaces. The module dimensions of the WEN025664A-CTP are 85.0 × 39.8 mm, and the active area is 69.1 × 17.26 mm. The model incorporates a projected capacitive touch panel (PCAP) with the FT6336U IC, supporting I2C interfaces and 1-point touch.
The WEN025664A-CTP OLED series operates on a 3V power supply with a driving method of 1/64 duty. It supports grayscales and boasts a high contrast ratio of 10,000:1. The module is capable of functioning in temperatures ranging from -20°C to +70°C, with a storage temperature range of -30°C to +80°C.
Featuring a metal frame with a PCB board and four screw holes, the WEN025664A-CTP facilitates easy installation for customers. The OLED series, equipped with a PCB board, can effortlessly connect with applications using wires, eliminating the need for customers to develop additional PCB boards. The integration of interface settings and VDD circuits enhances user-friendliness. Additionally, the four screw holes on the PCB simplify the installation process onto the application product.
The WEN025664A-CTP series also offers an option with the same OLED panel but without a touch panel. Please choose the WEN025664A series for the non-touch panel option.

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. |
||||||||||
7~14 | DB0 | I/O | Host Data Input/Output Bus These pins are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. When serial mode is selected, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. |
