产品叙述

华凌WEP012832A是一款2.23寸的COG+PCB OLED显示器模块,分辨率128x32 pixels。此款模块内建SSD1305Z IC,模块传输接口支持6800/8080 8-bit 并行接口、I2C与4-线SPI,同时适用3V~5V电压驱动。

WEP012832A模块是OLED COG结构并带有PCB版与铁框,机构上含有1个20 pin与1个8 pin金属单排PIN作为固定方式,同时客户也可选择用PCB版上螺丝孔当固定方式。同时,我们也提供使用排PIN+FPC(需要加Connector)或是Hot bar等方式供客户选择,不过成品料号会不同,如有需求请与我们联系进一步细节。另外,在模块上我们增加振动马达与蜂鸣器供客户使用。

此款模块非常适用智能家电、医疗产品、智能控制、量测仪器等产品。此模块的工作温度是-40℃至+80℃,储存温度-40℃至+85℃。

Pin功能定义

No. 符号 功能说明
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.
