Description

WEO012864A-CTP is a 1.54-inch COG structure Graphic OLED display with Capacitive Touch Panel on the module, resolution 128×64 pixels. This module is built-in with SSD1309 IC; it can be communicated via 6800/8080 8-bit parallel, 4-wire SPI, and I2C interface; supply voltage for logic is from 2.8V to 3.3V, typical value 3.0V, the supply voltage for display 12.5V, 1/64 driving duty. We provide two CTP options for this WEO012864A-CTP model; one CTP touch panel is by Air Bonding process, and the other CTP option is by Optical Bonding (OCA) process. These two CTP touch panel options are both built-in with FT6336U IC and support I2C interface with one detect point.

WEO012864A with the CTP model is ideal for smart home applications, intelligent technology devices, meter devices, industrial control systems, medical instruments, etc. This module can be operating at temperatures from -10℃ to +60℃; its storage temperatures range from -20℃ to +70℃.

The WEO012864A-CTP model OLED module features a high contrast ratio of 10,000:1, allowing for more vibrant and deeper blacks, and brighter whites. This results in enhanced image quality, sharper details, and improved readability.

BS2

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).

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.

D/C#

This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.

R/W#

This pin is read / write control input pin connecting to the MCU interface.
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH and write mode when LOW.
When 8080 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 chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.

E/RD#

This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal.
Read/write operation is initiated when this pin is pulled HIGH and the chip is selected.
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.

13-20

D0~D7

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: SDIN and D2 should be kept NC.
When I2C mode is selected, D2, D1 should be tied together and serve as SDAout, SDAin in application and D0 is the serial clock input, SCL.

IREF

This pin is the segment output current reference pin.
IREF is supplied externally.

VCOMH

COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.

VCC

Power supply for panel driving voltage. This is also the most positive power voltage supply pin.

NC(GND)

No connection
