SPI Display: Multifunctional text and graphic screens with serial interface
Multifunctional text and graphic displays with serial interface (SPI) and 4-bit/8-bit
With the EA DOG series, ELECTRONIC ASSEMBLY offers a product family with a wide range of different display sizes. These extremely compact COG (chip on glass) modules can be combined with various backlights and are therefore suitable for every conceivable application.
DOG displays have a very simple circuit design. The power supply is unproblematic, namely a genuine 3.3V operation for display and backlight. The control options are either parallel in 4-bit or 8-bit mode or serial with SPI. The SPI mode is particularly impressive with its speed and resource-saving manner. Serial mode only requires four host controller ports and can therefore also be connected to any existing SPI bus on the board.
Also worth mentioning is the low power consumption of 700 microamperes for the display and, depending on size and brightness, 10 to 150 milliamperes for the backlight.
