產品敘述
此款產品為型號WEP012832A OLED顯示模組加上電容式觸控面板，模組對角線尺寸為2.23吋並由128x32點矩陣組成顯示畫面。此OLED模組內建SSD1305IC，支援8bit 6800和8080 並列介面、I2C和4線SPI串列介面。模組邏輯電壓為3.3V，50%顯示畫面耗電流85mA，工作電壓3.3V (typical value)，driving duty 1/32，應用電壓適用3.0V~5.0V (VDD)。 模組使用的電容式觸控面板內建FT6336U IC支援I2C介面，支援單指觸控，使用亮面玻璃。
此顯示器為COG OLED顯示模組，模組上加上PCB設計。模組有排PIN與螺絲鎖孔等二種固定方式。此外，我們提供排PIN、FPC(需增加連接器)和Hot bar三種連接介面供客戶選擇，另外也提供小型振動馬達和蜂鳴讓客戶選配。
此款2.23吋繪圖型OLED顯示器適合用於智能家居應用、醫療設備、智能控制系統等。模組工作問度為-20℃至+70℃；儲存溫度為-40℃至+85℃。

Pin功能定義
| No. | 符號 | 功能說明 | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | VSS | Ground. | |||||||||||||||
| 2 | VDD | Power supply pin for core logic operation. | |||||||||||||||
| 3 | V0 | Keep float (i.e. disable). Power supply for panel driving voltage. This is also the most positive power voltage supply pin. | |||||||||||||||
| 4 | D/C# | This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDDIO), the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection. |
|||||||||||||||
| 5 | R/W# | This is read / write control input pin connecting to the MCU interface. When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH (i.e. connect to VDDIO) 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 interface is selected, this pin must be connected to VSS. |
|||||||||||||||
| 6 | E/RD# | When interfacing to a 6800-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect to VDDIO) and the chip is selected. When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected. When serial interface is selected, this pin must be connected to VSS. |
|||||||||||||||
| 7~14 | DB0~DB7 | These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus. 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 left opened. 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 | CS# | This pin is the chip select input. (active LOW) | |||||||||||||||
| 16 | RES# | This pin is reset signal input. When the pin is LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDDIO) during normal operation. |
|||||||||||||||
| 17,18 | BS1, BS2 | Communicating Protocol Select. These pins are MCU interface selection input. See the following table:
|

| 19 | N.C. | No connection. | |||||||||||||||
| 20 | FG(GND) | Ground. | |||||||||||||||
| 21 | TP_SCK | I2C Clock | |||||||||||||||
| 22 | TP_SDA | I2C Data | |||||||||||||||
| 23 | TP_INT | Interrupt Output This pin is used as the dedicated interrupt output signal. |
|||||||||||||||
| 24 | TP_RST | Hardware Reset This pin is to reset hardware for this chip. |
|||||||||||||||
| 25 | TP_VDD | Power supply pin for only touch panel (3.3V). | |||||||||||||||
| 26 | VSS | Ground. | |||||||||||||||
| 27 | N.C. | No connection. | |||||||||||||||
| 28 | N.C. | No connection. |
