WEN025664D-CTP model is an industrial grade 5.5-inch COF Graphic OLED with frame bezel, PCB and Capacitive Touchscreen, made of resolution 256x64 dots. This OLED module is built-in with SSD1322 IC; it supports 6800/8080 8-bit parallel, and 3-wire/4-wire SPI interface, supports 16 (4-bit) gray scale, supply voltage for logic 3V, the display current with 50% checkerboard is 240mA @3.0V VDD (typical value), 1/64 driving duty. This model is having Capacitive Touchscreen on module; it is built-in with GT911 IC which supports I2C interface, one detect point for CTP, normal glare surface glass.
The module is having PCB on module which is suitable for customers to use wire connection; customers do not need to develop extra PCB for their applications. Also, we integrated VCC circuit on PCB to make it easier for customers to use. This module is also supporting many wiring methods like PIN, FFC, CN, FPC. There are four mounting holes on PCB board which is an easy method for customers to fix modules on their applications.
This OLED module is suitable for smart home application, medical device, industrial control, etc. WEN025664D-CTP model can be operating at temperatures from -20°C to +70°C; its storage temperatures range from -30°C to +80°C.
This 5.5-inch OLED module is particularly suitable for applications such as POS systems and vending machines.
The Winstar COF Series is versatile, catering to applications in wall/meter devices, home applications, POS systems, Cloud/IoT systems, handheld instruments, intelligent technology devices, energy systems, automotive, communication systems, medical instruments, etc. Customers have the flexibility to upgrade their current applications from traditional STN displays to OLED displays, as Winstar provides a wide range of dot pixel formats for OLED solutions.

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.

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.
