Description
WEO012864AD is a 0.96-inch COG structure Graphic OLED display, made of resolution of 128x64 pixels. This module is built-in with ST7315 IC; it can be communicated via 6800 or 8080 parallel, 3/4-line SPI, and I2C interfaces; the supply voltage for display 12V (typical value), 1/64 driving duty, the supply voltage of logic is 3.0V (typical value), and the current with 50% checkerboard display is 6mA @ 3.0VCC (for white color). The WEO012864AD model is an IC alternative solution to the WEO012864D model; the electrical characteristics and PFC pin definition are the same. Customers have to adjust the initial code only. Winstar 0.96” OLED has many alternative options, such as WEO012864C with SH1106 IC, WEO012864AC with SSD1315 IC, and this WEO012864AD with ST7315 IC.
WEO012864AD model is ideal for smart home applications, financial-POS, Cloud/IoT systems, 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℃.
