产品叙述

WO240128B单色COG LCD液晶显示器是一款240x128点阵式4.8吋的绘图型模组。 WO240128B内建ST7586S 控制器IC, 支援多种传输介面: 6800 8-bit, 8080 8-bit 平行介面与3-线9-bit /4-线8-bit 串列SPI介面。 WO240128B为COG结构模组,其VA区尺寸以及AA区尺寸与现有华凌标准品COB结构的WG240128B相同,但WO240128B为COG结构,所以模组厚度较薄,外形轻巧,具有低功耗,低供电等特点,客户若有需求4.8吋模组的新案开发,建议可采用此WO240128B模组。

WO240128B的工作温度是-20℃至+70℃,储存温度-30℃至+80℃,此型号目前有STN Negative 负显, 与FSTN positive正显两种玻璃可供选择,可搭配LED白光,如有需求其他LCD或是LED背光组合可与我们联系。

Pin功能定义

Pin No. 符号 说明
1 ESD GND Electro-Static discharge
2 VG VG is the power of SEG-drivers
3 XV0 Negative operating voltage of COM-drivers
4 V0 Positive operating voltage of COM-drivers
5 VM VM is the non-select voltage level of COM-drivers
6 VDDA Power supply
7 VSS Ground
8 VD1 Digital power source selection
9 VDDI VDD1 is the power of interface I/O circuit
10 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)

IF3
IF2
IF1
These pins select interface operation mode

Note: Refer to “Interface Selection” for detailed information
14 RSTB Reset input pin. When RSTB is “L”, internal initialization procedure is executed
15 /RD(E) Read / Write execution control pin. (This pin is only used in parallelinterface)

This pin is not used in serial interfaces and should be connected to VDD1
16~23 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
24 /WR/(R/W) Read / Write execution control pin. (This pin is only used in parallel interface)

This pin is not used in serial interfaces and should be connected to VDD1
25 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
26 ESD GND Electro-Static discharge
