產品敘述

WEO012832K為2吋COG 帶Hot Bar FPC結構的繪圖型被動式OLED顯示器模組,面板解析度128x32 pixels。 WEO012832K模組內建SSD1315 IC,支援 6800/8080 8-bit 平行介面,I2C與4-線SPI介面,3V電壓驅動,1/32 duty。

WEO012832K與因為TAB IC EOL的WEX012832A產品AA區尺寸相同、PIN腳相容、客戶硬體不需修改,僅需修改Initial code,WEO012832K可視為WEX012832A替代方案。 WEO012832K是COG結構的OLED,無需背光非常輕薄 ,非常適用智能控制、工控儀器顯示器、智能家電、智能醫療等產品。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
1 NC No connection
2 VCC Power supply for panel driving voltage. This is also the most positive power voltage supply pin.
When charge pump is enabled, a capacitor should be connected between this pin and VSS.
3 VCOMH COM signal deselected voltage level.
A capacitor should be connected between this pin and VSS.
4 IREF This is segment output current reference pin.
When external IREF is used, a resistor should be connected between this pin and VSS to maintain the IREF current at 30uA.
5 D7 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.
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.

7 D5
8 D4
9 D3
10 D2
11 D1
12 D0
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 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 VDD) 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.
16 RES# This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin HIGH (i.e. connect to VDD) 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
BS[2:0] Interface
000 4 line SPI
001 3 line SPI
010 I2C
110 8-bit 8080 parallel
100 8-bit 6800 parallel
Note
(1) 0 is connected to VSS
(2) 1 is connected to VDD
20 BS1
21 VDD Power supply pin for core logic operation.
This is a voltage supply pin. It must be connected to external source.
22~29 NC No connection
30 VSS Ground pin. It must be connected to external ground.
31 NC No connection
