产品叙述

WO240128B2型号是WO240128B COG LCD模块加上PCB板,显示由240x128点阵组成。 模块内建ST7586S控制IC,默认8-bit 6800并列接口,另可选择支持8080并列接口或4线SPI、3线SPI 9-bit串行接口。电源电压为3.3V,驱动方式为1/128 duty 1/12 bias。 WO240128B2的优点是模块加上PCB板并含有四个螺丝锁孔,外围电路均在PCB上设计,这使模块可以更简单更易于使用在客户的应用产品上。 此外,还有三种连接器间距大小可供选择,分别为预设2.54mm以及可选1.0mm、0.5mm。另外此型号还可以选择VDD 5V电源电压。

WO240128B2模块工作温度为-20℃至+70℃; 储存温度为-30℃至+80℃。 模块为白色LED背光FSTN正显半透射式。 如果您需要不同类型的LCD或LED组合,请与我们联系。

产品规格

Pin功能定义

Pin No. 符号 说明
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-
