产品叙述
WEO012864MX是华凌光电发表的首款双色OLED图形模块，此模块为0.96吋的COG图形OLED显示模组128x64标准品，此型号内置SSD1306 IC，支援I2C, 3/ 4 wire SPI, 以及8 -bit parallel 接口。因为此款模块是OLED COG工艺所以厚度轻薄仅1.65 mm。 WEO012864MX标准品颜色只提供黄色/天空蓝，其他颜色则需客制。如果客户仅需要单色显示效果，建议可以选用同规格的WEO012864D。

| 5 | C1N | |||||||||||||||||||||||||
| 6 | VBAT | Power Supply for DC/DC Converter Circuit This is the power supply pin for the internal buffer of the DC/DC voltage converter. It must be connected to external source when the converter is used. It should be connected to VDD when the converter is not used. |
||||||||||||||||||||||||
| 7 | NC | NC | ||||||||||||||||||||||||
| 8 | VSS | Ground of Logic Circuit This is a ground pin. It acts as a reference for the logic pins. It must be connected to external ground. |

| 10 | BS0 | Communicating Protocol Select These pins are MCU interface selection input. See the following table:
|
||||||||||||||||||||||||
| 11 | BS1 | |||||||||||||||||||||||||
| 12 | BS2 | |||||||||||||||||||||||||
| 13 | CS# | Chip Select This pin is the chip select input. The chip is enabled for MCU communication only when CS# is pulled low. |
||||||||||||||||||||||||
| 14 | RES# | Power Reset for Controller and Driver This pin is reset signal input. When the pin is low, initialization of the chip is executed. |
||||||||||||||||||||||||
| 15 | D/C# | Data/Command Control This pin is Data/Command control pin. When the pin is pulled high, the input at D7~D0 is treated as display data. When the pin is pulled low, the input at D7~D0 will be transferred to the command register. For detail relationship to MCU interface signals, please refer to the Timing Characteristics Diagrams. When the pin is pulled high and serial interface mode is selected, the data at SDIN is treated as data. When it is pulled low, the data at SDIN will be transferred to the command register. In I2C mode, this pin acts as SA0 for slave address selection. |
||||||||||||||||||||||||
| 16 | R/W# | 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. |
||||||||||||||||||||||||
| 17 | E/RD# | 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. |
||||||||||||||||||||||||
| 18~25 | D0~D7 | 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. When I2C mode is selected, D2 & D1 should be tired together and serve as SDAout & SDAin in application and D0 is the serial clock input SCL. |
||||||||||||||||||||||||
| 26 | IREF | Current Reference for Brightness Adjustment This pin is segment current reference pin. A resistor should be connected between this pin and VSS. Set the current lower than 30uA. |
||||||||||||||||||||||||
