Description

WEO012864AE is a 1.54-inch COG 128x64 Graphic OLED display. This module is built-in with CH1116 IC; it can be communicated via I2C, 4-line SPI, 6800 or 8080 parallel interface; supply voltage for logic is 3V (typical value), the supply voltage for display 12.5V (typical value), 1/64 driving duty. WEO12864AE series has different ZIF FPC; currently, we provide 24 pins and 30 pins optional if customs require custom FPC, welcome to contact us.

WEO012864AE model is ideal for IoT systems, smart home applications, financial-POS, intelligent technology devices, energy systems, communication systems, medical instruments, etc. This module can be operating at temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃.

Interface Pin Function

No. Symbol Function
1 NC(GND) No connection
2 VSS Ground.
3 VSS Ground.
4 NC No connection
5 VDD1 Power supply input
6 IM1 These are the MPU interface mode select pads.
  8080 I2C 6800 4-wire SPI
IM1 1 1 0 0
IM2 1 0 1 0
Note
(1) 0 is connected to VSS
(2) 1 is connected to VDD1
7 IM2
8 CS# This pad is the chip select input. When CS# = “L”, then the chip select becomes active, and data/command I/O is enabled.
9 RES# This is a reset signal input pad. When RES# is set to “L”, the settings are initialized. The reset operation is performed by the RES# signal level.
10 A0 This is the Data/Command control pad that determines whether the data bits are data or a command.
A0 = “H”: the inputs at D0 to D7 are treated as display data.
A0 = “L”: the inputs at D0 to D7 are transferred to the command registers.
In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver.
11 WR#
(R/W#)
This is a MPU interface input pad.
When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU WR# signal. The signals on the data bus are latched at the rising edge of the WR# signal.
When connected to a 6800 Series MPU: This is the read/write control signal input terminal.
When R/W#= “H”: Read.
When R/W#= “L”: Write.
12 E/RD# This is a MPU interface input pad.
When connected to an 8080 series MPU, it is active LOW. This pad is connected to the RD# signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”.
When connected to a 6800 series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU.
When RD# = “H”: Enable.
When RD# = “L”: Disable.
13-20 D0~D7 This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus.
When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). At this time, D2 to D7 are set to high impedance.
When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance.
21 IREF This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75uA.
22 VCOMH OLED panel power supply. It could be supplied externally.
A capacitor should be connected between this pad and VSS.
23 VPP OLED panel power supply. Generated by internal charge pump.
Connect to capacitor. It could be supplied externally.
24 NC(GND) No connection
