Description

WEO012864AH is a 1.54-inch COG 128×64 graphic OLED display module. This OLED module is built-in with SH1106 IC; it can be communicated via I2C, 4-wire SPI, 6800 or 8080 interface. The supply voltage of logic is 1.65 V~ 3.3 V, and the typical value is 3.0V, supply voltage for display is 6.4V~ 13V(typical value 12.5V), 1/64 driving duty.

The WEO012864AH series 1.54-inch OLED modules from Winstar are ideal for a wide range of applications, including medical devices (pulse oximeter), consumer electronics (MP3 player, wireless microphone receiver), testing equipment (USB voltmeter) and industrial automation.

Key Features and Benefits:
High-quality displays: The WEO012864AH series offers high-quality OLED displays with excellent color accuracy, high contrast ratio (10,000:1), and resolution (128×64 dots) .
Compact size: The modules are designed with a compact size of 1.54 inches, making them ideal for use in portable devices and wearables.

Applications:
Medical devices: The WEO012864AH series is ideal for use in medical devices such as blood glucose meters, blood pressure monitors, and other healthcare devices.
Consumer electronics: The modules are suitable for use in a variety of consumer electronics, including smartwatches, fitness trackers, electronic vernier caliper and other wearables.
Industrial automation: The OLED displays can be used in industrial automation applications such as temperature and humidity sensors, and other monitoring devices.
Smart home devices: The modules can be used in smart home devices such as lighting systems, and other IoT devices.

This module can be operating at temperatures from -40℃ to +80℃; its storage temperatures range from -40℃ to +85℃. WEO012864AH series has different ZIF FPC; currently, we provide 24 pins and 30 pins optional if customs require custom FPC, welcome to contact us.

WEO012864AH is well-suited for pulse oximeters, wireless microphone receivers, and USB voltmeters.

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/= “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 This is a pad for the voltage output high level for common signals.
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 ESD_GND ESD Ground pin
