Description

WO12864N is a 128x64 COG Graphic LCD display. This LCD module is built in with ST7567 controller IC, driving duty 1/65. It supports 6800 8-bit, 8080 8-bit parallel and 4-line SPI interface. This LCD module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. WO12864N is COG structure display that is very suitable for applications that demand a more compact package. Please note the WO12864N is the alternative model for WO12864B1 corresponding IC shortage or longer lead-time.

Fonction PIN sur l'interface

Pin	Symbole	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.

20	V0	V0 is the LCD driving voltage for common circuits at negative frame.
21	XV0	XV0 is the LCD driving voltage for common circuits at positive frame.
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.
30	NC	Not connect.
