產品敘述
WEN025664A-CTP為一款2.8吋單色圖形COF OLED顯示模組，搭載投射式電容觸控面板（PCAP），解析度為256×64 dots。本模組採用SSD1322驅動IC，支援6800/8080 8-bit平行介面與3/4線SPI介面。模組外形尺寸為85.0 × 39.8 mm，顯示區域為69.1 × 17.26 mm。觸控面板採用FT6336U控制器，支援I²C介面與單點觸控。
本OLED模組採用3V電源供應，並以1/64 duty驅動方式運作，支援灰階顯示，對比度可達10,000:1。操作溫度範圍為-20°C至+70°C，儲存溫度範圍為-30°C至+80°C。
WEN025664A-CTP採用金屬框架搭配PCB一體化設計，並提供4個固定孔位，有助於機構整合與安裝。由於介面設定與VDD電源電路已整合於PCB上，可透過線材直接與系統連接，有助於簡化系統設計並降低額外轉接板需求。
WEN025664A-CTP系列亦提供無觸控版本。如需非觸控面板選項，請參考WEN025664A系列。

Pin功能定義
| Pin Number | 符號 | I/O | 功能說明 | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 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, D1 will be the serial data input SDIN and D0 will be the serial clock input SCLK. |
