產品敘述

華凌WEP012832A是一款2.23吋的COG+PCB OLED顯示器模組,解析度128x32 pixels。此款模組內建SSD1305 IC,模組傳輸介面支援6800/8080 8-bit 平行介面、I2C與4-線SPI,同時適用3V~5V電壓驅動。

WEP012832A模組是OLED COG結構並帶有PCB版與鐵框,機構上含有1個20 pin與1個8 pin金屬單排PIN作為固定方式,同時客戶也可選擇用PCB版上螺絲孔當固定方式。同時,我們也提供使用排PIN+FPC(需要加Connector)或是Hot bar等方式供客戶選擇,不過成品料號會不同,如有需求請與我們聯繫進一步細節。另外,在模組上我們增加振動馬達與蜂鳴器供客戶使用。

此款模組非常適用智能家電、醫療產品、智能控制、量測儀器等產品。此模組的工作溫度是-40℃至+80℃,儲存溫度-40℃至+85℃。

Pin功能定義

No. 符號 功能說明
1 VSS Ground.
2 VDD Power supply pin for core logic operation.
3 V0 Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
4 D/C# This is Data/Command control pin. When it is pulled HIGH (i.e. connect to VDDIO), the data at D[7:0] is treated as data. When it is pulled LOW, the data at D[7:0] will be transferred to the command register.
In I2C mode, this pin acts as SA0 for slave address selection.
5 R/W# This is read / write control input pin connecting to the MCU interface.
When interfacing to a 6800-series microprocessor, this pin will be used as Read/Write (R/W#) selection input. Read mode will be carried out when this pin is pulled HIGH (i.e. connect to VDDIO) 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 interface is selected, this pin must be connected to VSS.
6 E/RD# When interfacing to a 6800-series microprocessor, this pin will be used as the Enable (E) signal. Read/write operation is initiated when this pin is pulled HIGH (i.e. connect to VDDIO) and the chip is selected.
When connecting to an 8080-microprocessor, this pin receives the Read (RD#) signal. Read operation is initiated when this pin is pulled LOW and the chip is selected.
When serial interface is selected, this pin must be connected to VSS.
7~14 DB0~DB7 These are 8-bit bi-directional data bus to be connected to the microprocessor’s data bus.
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 left opened. 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.
15 CS# This pin is the chip select input. (active LOW)
16 RES# This pin is reset signal input. When the pin is LOW, initialization of the chip is executed.
Keep this pin HIGH (i.e. connect to VDDIO) during normal operation.
17,18 BS2,BS1 Communicating Protocol Select.
These pins are MCU interface selection input. See the following table:
  68XX-parallel 80XX-parallel Serial I2C
BS1 0 1 0 1
BS2 1 1 0 0
19 N.C. No connection.
20 FG(GND) Ground.
21~25 N.C. No connection.
26 VSS Ground.
27 BSW Control the Piezoelectric Buzzer.
28 MSW Control the BLDC Vibration Motor.
