Description

The WEN025664D COF OLED display module, which includes a frame and PCB, features a resolution of 256×64 dots and a 5.5-inch diagonal module dimension (135.65 × 33.89 mm). Equipped with a built-in SSD1322 IC supporting 6800/8080 8-bit and 3/4-line SPI interfaces, this module operates on a 3V power supply, utilizing a 1/64 duty driving method and supporting 4-bit grayscale with an impressive contrast ratio of 10000:1.

The OLED series comes with a PCB board featuring a frame, facilitating convenient connectivity to applications via wires. Customers are spared the task of developing additional PCB boards, as the module integrates interface settings and VDD circuits for user-friendly operation. The PCB also includes four screw holes, streamlining the installation onto application products. With an operational temperature range of -40℃ to +80℃ and a storage temperature range of -40℃ to +85℃, this OLED module is well-suited for diverse environments.

Additional OLED panel options include:

  • WEX025664D: OLED panel only.
  • WEN025664D-CTP: Equipped with a frame, PCB, and CTP touch panel.

 

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.

Interface Pin Function

Pin
Number		 Symbol I/O Function
1 VSS P Ground.
2 VDD P Power Supply for Core Logic Circuit
Power supply pin for core logic operation. A capacitor is required to connect between this pin and VSS
3 N.C. P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
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.

15 NC P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
16 RES# I This pin is reset signal input.
When the pin is pulled LOW, initialization of the chip is executed.
Keep this pin pull HIGH during normal operation.
17 CS# I Data/Command Control
This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW.
18 NC P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
19 BS1 I Communicating Protocol Select
These pins are MCU interface selection input. See the following table:

BS[1:0] Bus Interface Selection
00 4 line SPI
01 3 line SPI
10 8-bit 8080 parallel
11 8-bit 6800 parallel
