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.

Interface Pin Function

Pin No. Symbol Description
1 VDD Power supply pin for logic.
2 VSS Ground pin, connected to 0V
3 CSB Chip select input pin.
4 NC NC
5 RSTB Hardware reset input pin
6 A0 It determines whether the access is related to data or
command.
7 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.
RWR is not used 4-line SPI interface and should fix to “H” by VDD
8 ERD
C86 MPUType 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 4-Line SPI interface and should fix to “H” by VDD
9~16 D0~D7 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
When using serial interface: 4-line SPI
D[0]=SCL: Serial clock input.
D[1]=SDA_IN: Serial data input.
D[2:3]=SDA_OUT: Serial data output.
D[1:3] must be connected together as SDA.
D[4:7]=(1,1,1,1): ID Pin. D[4:7] should fix to “H” or “L” by VDDH or VSSL.
ID[0:3] can be read 4-bit ID only for serial interface from D[4:7].
17 C86 C86 selects the microprocessor type in parallel interface mode.
PSB C86 Selected Interface
“L” “H” Serial 4-Line SPI Interface
“H” “L” Parallel 8080 Series MPU Interface
“H” “H” Parallel 6800 Series MPU Interface
18 PSB PSB selects the interface type: Serial or Parallel.
