產品敘述
WEP012864Q系列是一款2.7吋單色繪圖型COG OLED顯示器模組，解析度為128x64像素。 它內建SSD1309控制器IC，透過6800 8-bit/8080 8-bit並列介面或I2C/4線SPI串行介面進行通信，使用3V電壓驅動。 WEP012864Q的模組尺寸為82.0×47.5 mm，有效區域為61.41×30.69 mm。 此系列採用與現有的WEO012864Q和WEF012864Q使用相同的OLED面板。
WEO012864Q 系列特點是無鐵框和PCB設計。
WEF012864Q 系列搭配鐵框，鐵框上設計四個螺絲孔，可增加結構穩定性。
WEP012864Q 系列是同時具有鐵框和PCB，PCB上整合有四個螺孔，以便於安裝。
這三種不同的結構可滿足不同客戶的應用需求，為不同的設計考慮和安裝偏好提供選項。如果需要觸控功能，請考慮在這個系列中選擇 WEP012864Q-CTP 型號
OLED COG顯示器模組因為非常的薄，重量輕巧且低耗電流並具有10,000:1的高對比度，所以非常適合手持式產品、量測儀器、智慧電表、穿戴式產品、物聯網設備等。WEP012864Q OLED模組可在-40℃至+80℃的溫度下工作； 其儲存溫度範圍為-40℃至+80℃。

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | VSS | Ground. | |||||||||||||||

| 5 | R/W# (WR#) |
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. |
|||||||||||||||
| 6 | 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. |
|||||||||||||||
| 7-14 | 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. |

| 15 | NC | No connection | |||||||||||||||
| 16 | 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. |
|||||||||||||||
| 17 | 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). |

| 18 | NC | No connection | |||||||||||||||
| 19 | BS2 | MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2 and BS1 are pin select
(1) 0 is connected to VSS (2) 1 is connected to VDD |
