Description

WO12864N is a 2.82-inch 128x64 monochrome Chip on Glass (COG) LCD module featuring the ST7567 controller IC. The module is available with 6800 8-bit, 8080 8-bit parallel, or 4-line SPI interface options and operates from a 3 V power supply.

The module measures 89.7 x 49.8 x 6.0 mm, with a 69.0 x 36.5 mm view area and a 63.97 x 31.97 mm active area. It operates with a 1/65 duty cycle and 1/9 bias drive scheme.

With an operating temperature range of -20°C to +70°C and a storage temperature range of -30°C to +80°C, this graphic COG LCD module is available with an LED backlight. Other LCD types and LED backlight combinations are also available upon request. Click Add to Inquiry above and specify your requirements in the inquiry message.

WO12864N shares the same mechanical dimensions, view area, and active area as the WO12864B1. Featuring the ST7567 controller IC, it is designed for applications requiring the same module footprint with support for 6800, 8080, or 4-line SPI interface options.

Interface Pin Function

Pin	Symbol	Description
1	CSB	Chip select input pin.Interface access is enabled when CSB is “L”,When CSB is non-active(CSB=”H”),D[7:0] pins are high impedance.
2	RSTB	Hardware reset input pin. When RSTB is “L”, interna initialization is executed and the internal registers will be initialized.
3	A0	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
4	RWR	Read/Write execution control pin. When PSB is “H”, RWR is not used in serial interface and should fix to “H” by VDD1 or VDDH.
5	ERD	Read/Write execution control pin. When PSB is “H”, ERD is not used in serial interface and should fix to “H” by VDD1 or VDDH.
6	D0	When using 8-bit parallel interface: (6800 or 8080 mode) 8-bit bi-directional data bus. Connect to the data bus of 8-bit microprocessor. When CSB is non-active (CSB=“H”), D[7:0] pins are high impedance.

22	VG	VG is the LCD driving voltage for segment circuits.
23-27	NC	Not connect.
28	C86	C86 selects the microprocessor type in parallel interface mode.
29	PSB	PSB selects the interface type: Serial or Parallel.
