Graphic OLED Display 3.12 inch SPI Interface Product Introduction
Description
The SFOM312YZ7-25664WBYG-01 model is a COF Graphic OLED, featuring a diagonal size of 3.12 inches and a resolution of 256x64 dots. This OLED module is built-in with the SSD1322 IC and supports 8-bits 6800/8080 and 3/4-line SPI interfaces. It has an outline dimension of 100.5 × 33.5.0 mm, with an active area size of 76.78 × 19.18 mm. It also supports 4-bits grayscale, with a logic supply voltage of 3V. The display's current at 50% check board is 150mA @3.0V VDD (typical value), with a driving duty of 1/64.
The module has a built-in PCB, allowing customers to use wire connections without the need for additional PCB development for their applications. Additionally, the integrated VCC circuit on the PCB simplifies customer usage. This PCB board, equipped with four mounting holes, provides an easy method for customers to secure modules in their applications. This OLED module is suitable for smart home applications, medical devices, industrial control, etc.

5 |
RES
|
This pin is reset signal input. When the pin is pulled LOW, initialization of the chip is executed. Keep this pin pull HIGH during normal operation. |
|
6 |
DC |
This pin is Data/Command control pin connecting to the MCU. When the pin is pulled HIGH, the data at D[1:0] will be interpreted as data. When the pin is pulled LOW, the data at D[1:0] will be transferred to a command register. |
|
7 |
CS |
This pin is the chip select input connecting to the MCU. The chip is enabled for MCU communication only when CS# is pulled LOW (active LOW |
