产品叙述

WO12864T是一款单色128x64点阵式COG绘图型LCD液晶显示器模块。此款COG LCD模块内置ST7565P IC, 支持 8-bit 6800, 8-bit 8080 并行接口与4线SPI串行接口。WO12864T的模块外观尺寸与WX12864T2相同，但是两者VA区尺寸与AA区尺寸稍微有些差异，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。WO12864T是TAB结构WX12864T2的替代方案，此款型号的TAB IC已经停产，原本使用TAB 结构WX12864T2产品应用建议可以改用此款COG 结构WO12864T替代。

WO12864T的工作温度是-20℃至+70℃，储存温度-30℃至+80℃。WO12864T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

VDD

Power supply pin for logic.

VSS

Ground pin, connected to 0V

/CS1

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.

CS2

/RES

Hardware reset input pin. When RSTB is "L", internal initialization is executed and the internal registers will be initialized.

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.

R/W

Read/Write execution control pin. When PSB is "H",
RWR is not used in serial interface and should fix to "H" by VDD.

C86	MPU Type	RWR	说明
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.

Read/Write execution control pin. When PSB is "H",

C86	MPU Type	ERD	说明
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.

D0-D7

I/O

Data bus line

C86

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.

P/S

PSB selects the interface type: Serial or Parallel.
