EA OLEDM204 EA OLED SERIES With its EA OLED series ELECTRONIC ASSEMBLY launches worldwide the first display family with OLEDtechnology for direct mounting and soldering. In comparison to standard displays there’s no FFC/FPC cable/connector that may loose contact, this OLED series will be soldered directly or put into a standard 2.54 mm precision socket.

EA OLEDM204 DATA TRANSFER 3-WIRE SPI (8 BIT) Data transmission for SPI is unidirectional, that means that data can only be written, there’s no data read option. Selection for writing data or command is done with the DC bit. A busy check is not necessary at all. Clock rate may be up to 1 MHz. Data transmission is based on SPI mode 3, MSB first. For more details please refer to the controllers data sheet SSD1311.
