Description

Le WO12864B est un module LCD graphique monochrome COG de 2,8 pouces avec une résolution de 128x64. Ce module LCD est intégré avec un contrôleur ST7565P ou un circuit intégré équivalent. Il prend en charge les interfaces parallèles 8 bits 6800 et 8080 ainsi que l'interface SPI. Ce module LCD peut fonctionner à des températures allant de -20℃ à +70℃, et ses températures de stockage vont de -30℃ à +80℃. Cet écran COG WO12864B est très adapté aux applications nécessitant des affichages dans des emballages plus compacts.

Il existe deux versions de la série WO12864B, qui diffèrent par leur épaisseur comme suit :

►WO12864B : thickness 12.1mm (Max)
►WO12864B1 : thickness 6.0mm

Fonction PIN sur l'interface

Pin No. Symbole Level Description
1 /CS1B I This is the chip select signal.
2 /RES I When RES is set to “L”, the setting are initialized.
3 A0 I This is connect to the least significant bit of the normal MPU address bus, and it determines whether the data bits are data or command.
A0 = “H”: Indicates that D0 to D7 are display data.
A0 = “L”: Indicates that D0 to D7 are control data.
4 /WR(R/W) I • When connected to 8080 series MPU, this pin is treated as the “/WR” signal of the 8080 MPU and is LOW-active.
The signals on the data bus are latched at the rising edge of the /WR signal.
• When connected to 6800 series MPU, this pin is treated as the “R/W” signal of the 6800 MPU and decides the access type :
When R/W = “H”: Read.
When R/W = “L”: Write.
5 /RD(E) I

• When connected to 8080 series MPU, this pin is treated as the “/RD” signal of the 8080 MPU and is LOW-active.
The data bus is in an output status when this signal is “L”.
• When connected to 6800 series MPU, this pin is treated as the “E” signal of the 6800 MPU and is HIGH-active.
This is the enable clock input terminal of the 6800 Series MPU.
6~13 D0~D7 I/O Data bus line
14 VDD Power supply Power supply
15 VSS Power supply Ground
16 VOUT O DC/DC voltage converter. Connect a capacitor between this terminal and vss or VDD
17 CAP3P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
18 CAP1N O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1P terminal.
19 CAP1P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP1N terminal.
20 CAP2P O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2N terminal.
21 CAP2N O DC/DC voltage converter. Connect a capacitor between this terminal and the CAP2P terminal.
22~26 V4~V0 Power supply This is a multi-level power supply for the liquid crystal drive.
27 VR I Output voltage regulator terminal. Provides the voltage between VSS and V0 through a resistive voltage divider.
28 C86 I This is the MPU interface selection pin.
C86 = “H”: 6800 Series MPU interface.
C86 = “L”: 8080 Series MPU interface
29 P/S I This is the parallel data input/serial data input switch terminal.
P/S = “H”: Parallel data input.
P/S = “L”: Serial data input.
The following applies depending on the P/S status:
P/S Data/Command Data Read/Write Serial Clock
"H" A0 D0 to D7 /RD,/WR X
"L" A0 SI(D7) Write only SCL(D6)
When P/S = “L”, D0 to D5 fixed “H”.
/RD (E) and /WR (R/W) are fixed to either “H” or “L”.
With serial data input, It is impossible read data from RAM
30 NC - No connection.
