WEA025664A is a COG Graphic OLED with PCB on module, which is made of resolution 256x64 pixels, diagonal size 2.08 inch. This PCB board with four mounting holes is easy-to-use for customers to fix modules on their applications. WEA025664A OLED module is equipped with SSD1362 driver IC that enables using SPI interface. This model is optional for integrating with a Font IC of GT21L16T1W for traditional Chinese which supports SPI interface. The GT21L16T1W is a 15x16 dots fonts chip; it supports Chinese standard GB12345 traditional Chinese character set, BIG5 traditional Chinese character basic set, Japanese standard JIS0208 Japanese character set (compatible with Unicode), and a total of 150 countries’ character. The supply voltage for logic of WEA025664A is 3V or 5V, supports 16 gray scale (4bits), driving duty 1/64, the display with 50% check board current is 90mA@3.3VDD (typical value).

This OLED module is suitable for smart home application, medical device, smart control and etc. WEA025664A module can be operating at temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃.

Interface Pin Function

No. Symbol Function
1 GND Reserved pin. It should be connected to ground.
2 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin. It is supplied by external high voltage source.
3 D0 These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
When serial interface mode is selected, D0 will be the serial clock input: SCLK; D1 will be the serial data input: SID.
4 D1
5 RES# 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.
6 D/C# This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[1:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[1:0] will be transferred to a command register.
7 CS# This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
