Description

The WEN025664A series is a 2.8-inch monochrome graphic COF OLED display 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 are 85.0 × 39.8 mm, and the active area is 69.1 × 17.26 mm.

The WEN025664A OLED series operates on a 3V power supply with a driving method of 1/64 duty. It supports grayscale and boasts a high contrast ratio of 10,000:1. The module is capable of functioning in temperatures ranging from -40°C to +80°C, with a storage temperature range of -40°C to +83°C.

Featuring a metal frame with a PCB board and four screw holes, the WEN025664A 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 series also offers an option with the same OLED panel but with a touch panel. Please choose the WEN025664A-CTP series for the touch panel option.

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, DB1 will be the serial data input SDIN and DB0 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
Note
(1) 0 is connected to VSS
(2) 1 is connected to VDD
20 BS0
21~24 NC P Reserved Pin
The N.C. pin between function pins are reserved for compatible and flexible design.
