产品叙述

WEO012864Q 是一款2.7吋无铁框的COG 图型单色被动式OLED显示器模块,面板分变率128x64 pixels。 WEO012864Q内置SSD1309ZC controller控制器, 支援多种传输接口: 6800 8-bite, 8080 8-bit 平行接口, I2C 与4线SPI串列接口,使用3V驱动。 WEO012864Q的模块尺寸为73.0 x 41.86 mm, AA区尺寸为61.41 x 30.69 mm,此款型号与现有的WEO012864K使用相同的OLED面板,但FPC出pin与定义同WEX012864L(30 pins)。 

WEO012864Q为COG结构的OLED显示器模块,为有机自发光,无须背光源,模组轻薄且低耗电流,WEF012864Q模块非常适合手持式产品、量测仪器、家用产品、POS系统、物联网、通讯设备与医疗仪器等等。此模组的工作温度是-40℃至+80℃,储存温度-40℃至+80℃。

  • WEO012864QW : 白色
  • WEO012864QL : 黄色
  • WEO012864QS : 天空蓝 (might have MOQ)

Pin功能定义

No. 符号 功能说明
1 NC  No connection
2 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
3 VCOMH COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
4 IREF This pin is the segment output current reference pin. IREF is supplied externally.
5~12 D7~D0 These pins are bi-directional data bus connecting to the MCU data bus.
Unused pins are recommended to tie LOW.
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 kept NC.
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.
13 E/RD# This pin is MCU interface input.
When 6800 interface mode is selected, this pin will be used as the Enable (E) signal.
Read/write operation is initiated when this pin is pulled HIGH and the chip is selected.
When 8080 interface mode is selected, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial or I2C interface is selected, this pin must be connected to VSS.
14 R/W# This pin is read / write control input pin connecting to the MCU interface.
When 6800 interface mode is selected, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH 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 or I2C interface is selected, this pin must be connected to VSS.
15 D/C# This pin is Data/Command control pin connecting to the MCU.
When the pin is pulled HIGH, the data at D[7:0] will be interpreted as data.
When the pin is pulled LOW, the data at D[7:0] will be transferred to a command register.
In I2C mode, this pin acts as SA0 for slave address selection.
When 3-wire serial interface is selected, this pin must be connected to VSS.
16 RES# 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# This pin is the chip select input connecting to the MCU.
The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW).
18 NC No connection
19 BS2 MCU bus interface selection pins. Select appropriate logic setting as described in the following table. BS2, BS1 and BS0 are pin select

Note
(1) 0 is connected to VSS
(2) 1 is connected to VDD
20 BS1
21 VDD Power supply pin for core logic operation
22~28 NC No connection
29 VSS Ground.
30 NC No connection
