Microchip 24LCS22A documentation, 317 KB in PDF, indexed as a schematic but in reality the part datasheet. The 24LCS2x family are display data channel EEPROMs used to hold monitor EDID information, so this sheet is relevant to monitors, TVs and display boards. It should explain the DDC modes, pinout and I2C operation. Useful when a screen is not recognised by the source and the EDID chip needs reading or rewriting with a programmer. Save the original EDID before writing a replacement image.
