Description

WEN025664B-CTP model is a COF Graphic OLED with Capacitive Touch, featuring a diagonal size of 3.12 inches and a resolution of 256x64 dots. This OLED module is built-in with the SSD1322 IC and supports 8-bits 6800/8080 and 3/4-line SPI interfaces. It also supports 4-bits grayscale, with a logic supply voltage of 3V. The display's current at 50% check board is 150mA @3.0V VDD (typical value), with a driving duty of 1/64. The model includes a capacitive touch panel with the FT6336U IC supporting an I2C interface, one detect point for CTP, and a normal glare surface glass.

The module has a built-in PCB, allowing customers to use wire connections without the need for additional PCB development for their applications. Additionally, the integrated VCC circuit on the PCB simplifies customer usage. This PCB board, equipped with four mounting holes, provides an easy method for customers to secure modules in their applications. This OLED module is suitable for smart home applications, medical devices, industrial control, etc.

The WEN025664B-CTP model can operate at temperatures ranging from -20℃ to +70℃, with storage temperatures ranging from -30℃ to +80℃. The OLED module features a high contrast ratio of 10,000:1, resulting in enhanced image quality, sharper details, and improved readability, especially in low-light environments.

Additionally, the product line of the same OLED panels offers various alternatives:
  • WEX025664B series without a metal frame, PCB, and touch screen.
  • WEX025664B-CTP series without a metal frame, PCB, and with a CTP touch screen.
  • WEN025664B series with a metal frame and PCB.

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 electioin
00 4 line SPI
01 3 line SPI
10 8-bit 8080 parallel
11 8-bit 6800 parallel
