Description

WO12864T1 is a monochrome graphic LCD module made of 128x64 dot matrix format. This COG module is built in with ST7567S IC, it supports 8-bit 6800, 8-bit 8080 parallel and 4-wire serial SPI interface, 1/65 driving duty, 1/9 Bias. WO12864T1 is the alternative model for WO12864T corresponding IC shortage or longer lead-time. This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. This LCD COG 128x64 display is very suitable for applications that demand more compact package displays.

Description

VDD

Power supply pin for logic.

VSS

Ground pin, connected to 0V

CSB

Chip select input pin.

RSTB

Hardware reset input pin

It determines whether the access is related to data or
command.

RWR

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.

ERD

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.
