產品敘述
WEN025664B型號是一款COF結構的繪圖型OLED模組，對角線尺寸為3.12吋，解析度由256x64 dots組成。該OLED模組內建SSD1322 IC支援4-bit灰階和8-bits 6800/8080和3/4線SPI介面。外形尺寸為89.2×44.0 mm，有效顯示區域尺寸為76.78×19.18 mm。模組邏輯電壓為3V，50%顯示畫面時耗電流為150 mA @ VDD 3.3V(典型值)，驅動方式1/64 duty。OLED模組加上PCB設計可使用導線連接，客戶不需要額外自行開發PCB版，其整合了介面設定和VDD電路，使客戶易於使用。PCB板設計四個螺絲孔方便使用者將模組固定在應用產品上。
WEN025664B模組工作溫度為-40℃~+80℃;儲存溫度為-40℃~+85℃。此OLED模組具有10,000:1的高對比度，可提高圖像質量，使細節更加清晰，尤其在低光環境中閱讀性更強。COF OLED模組適用於醫療設備、控制面板、智能家居等產品應用。
此外，具有相同尺寸的OLED面板還提供各種替代方案：- WEX025664B系列，無鐵框、PCB、觸控面板。
- WEX025664B-CTP系列，無鐵框、PCB，配備電容式觸控面板。
- WEN025664B-CTP系列，配備鐵框、PCB、電容式觸控面板。

|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 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. |
