产品叙述

华凌发表一款单色绘图型COG LCD模块WO12864U,此款COG液晶显示器为128x64点阵式LCM模块。WO12864U内置ST7565P IC, 支援 8-bit 6800, 8-bit 8080 并行接口与4线SPI串行接口。WO12864U的模块外观尺寸及VA区尺寸与AA区尺寸都与TAB 结构的WX12864U2相同。两款产品的驱动电压同样都是3.3V (VDD),VOP同样是9.1V,主要电气特性相同。WO12864U是TAB结构WX12864U2的替代方案,此款TAB IC已经停产,原本使用WX12864U2产品应用建议可以改用此款COG结构WO12864U替代。

WO12864U的工作温度是-20℃至+70℃,储存温度-30℃至+80℃。WO12864U型号目前有FSTN positive玻璃可供选择,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 I/O 说明
1 VDD ­_ Power supply pin for logic.
2 VSS _ Ground pin, connected to 0V
3 /CS1 I Chip select input pin. Interface access is enabled when CS1B is "L" and CB2 is "H" . When chip is on-active (CS1B="H" or CS2="L"), D[7:0] pins are high impedance.
4 CS2
5 /RES I Hardware reset input pin. When RSTB is "L", internal initialization is executed and the internal registers will be initialized.
6 A0 I It determines whether the access is related to data or command.
A0=“H”: Indicates that signals on D[7:0] are display data.
A0=“L”: Indicates that signals on D[7:0] are command.
7 R/W I Read/Write execution control pin. When PSB is "H",
C86 MPU Type RWR Description
H 6800 series R/W Read/Write control input pin.
R/W="H": read
R/W="L": write
L 8080 series /WR Write enable input pin.
Signals on D[7:0] will be latched at the rising edge of /WR signal.

RWR is not used in serial interface and should fix to "H" by VDD.
8 E I Read/Write execution control pin. When PSB is "H",
C86 MPU Type ERD Description
H 6800 series E Read/Write control input pin.
R/W="H": When E is "H", D[7:0] are in output mode.
R/W="L": Signals on D[7:0] are latched at the falling edge of E signal
L 8080 series /RD Read enable input pin.
When /RD is "L", D[7:0] are in output mode.

ERD is not used in serial interface and should fix to "H" by VDD.
9-16 D0-D7 I/O Data bus line
17 C86 I C86 selects the microprocessor type in parallel interface mode.
PSB C86 Selected Interface
"H" "H" Parallel 6800 Series MPU Interface
"H" "L" Parallel 8080 Series MPU Interface
"L" "X" Serial 4-Line SPI Interface

Please refer to “APPLICATION NOTES” and “Microprocessor Interface” (Section 6) for detailed connection of the selected interface.
18 P/S I PSB selects the interface type: Serial or Parallel.
