产品叙述
WEN025664D COF OLED显示模块配备铁框和PCB，分辨率为256x64 dots，模块对角线5.5寸(有效区域尺寸:135.65 × 33.89 mm)。 此模块内建SSD1322 IC，支持6800/8080 8-bits和3/4线SPI接口，工作电压为3V，驱动方式1/64 duty，支持4-bits 灰阶，具高对比度度为10000:1，能呈现清晰的显示效果。
此系列OLED模块加上PCB设计可使用导线连接，客户不需要额外自行开发PCB版，其整合了接口设定和VDD电路，使客户易于使用。PCB上设计了四个螺丝孔使客户更容易将模块安装于应用产品上。此OLED模块的工作温度范围为-40℃至+80℃，储存温度范围为-40℃至+85℃，非常适合多种环境。
同样的OLED面板还有其他的选项：- WEX025664D：仅OLED面板。
- WEN025664D-CTP：搭配铁框和PCB板以及CTP触控面板。
因为此款模块是OLED COF 结构自发光无须背光，所以厚度也非常的薄仅2.05 mm。 此5.5” OLED模块目前量产色有绿色与黄色，非常适合运用在POS系统。
Winstar COF OLED模块系列非常适合墙面型(wall devices) 与测量仪器(meter devices)，例如POS系统、云端/物联网系统、手持式产品、智能科技与智能能源系统、车载与通讯设备以及医疗仪器等等，客户能便利地将原来产品上的STN显示器轻易地升级到OLED显示器，因为华凌光电提供非常多样化与广度的OLED尺寸与OLED产品提升解决方案供客户产品升级。

符号 | I/O | 功能说明 | ||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 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. |

| 16 | RES# | I | 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# | I | Data/Command Control This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW. |
