產品敘述

WO240128B2型號是WO240128B COG LCD模組加上PCB板,顯示由240x128點陣組成。 模組內建ST7586S控制IC,預設8-bit 6800並列介面,另可選擇支援8080並列介面或4線SPI、3線SPI 9-bit串列介面。電源電壓為3.3V,驅動方式為1/128 duty 1/12 bias。 WO240128B2的優點是模組加上PCB板並含有四個螺絲鎖孔,外圍電路均在PCB上設計,這使模組可以更簡單更易於使用在客戶的應用產品上。此外,還有三種連接器間距大小可供選擇,分别為預設2.54mm 以及可選1.0mm、0.5mm。 另外此型號還可以選擇VDD 5V電源電壓。

WO240128B2模組工作溫度為-20℃至+70℃; 儲存溫度為-30℃至+80℃。 模組為白色LED背光FSTN正顯半透射式。 如果您需要不同類型的LCD或LED組合,請與我們聯繫。

產品規格

Pin功能定義

Pin No. 符號 說明
1 VDD Power supply
2 NC No connection
3 VSS Ground
4 CSB Chip select input pin
CSB=“L”: This chip is selected and the MPU interface is active
CSB=“H”: This chip is not selected and the MPU interface is disabled
(D[7:0] are high impedance)
5 RSTB Reset input pin. When RSTB is “L”, internal initialization procedure is executed
6 /RD(E) Read / Write execution control pin. (This pin is only used in parallelinterface)
MPU Type ERD Description
6800-series E Read/Write control input pin.
R/W = "H": When E is "H", data bus is in output status.
R/W = "L": The data are latched at the falling edge of the E signal.
8080-series /RD Read enable input pin.
When /RD is "L", data bus is in out put status.
This pin is not used in serial interfaces and should be connected to VDD1
7~14 D7~D0 The bi-directional data bus of the MPU interface. When CSB is “H”, they are high impedance
If using serial interface:
D0 is the SDA signal in 4-Line & 3-Line interface
D1 is the A0 signal in 4-Line interface
15 /WR/(R/W) Read / Write execution control pin. (This pin is only used in parallel interface)
MPU Type ERD Description
6800-series R/W Read/Write control input pin.
R/W = "H": read
R/W = "L": write
8080-series /WR Read enable input pin.
The data are latched at the rising edge of the /WR signal.
This pin is not used in serial interfaces and should be connected to VDD1
16 A0(SCL) The function of this pin is different in parallel and serial interface
In parallel interface: A0 is register selection input
A0 = "H": inputs on data bus are display data
A0 = "L": inputs on data bus are command
In serial interface: this pad will be used as SCL (serial-clock) input
17 A LED+
18 K LED-
