The CAT24C21 is a 1-kb Serial CMOS EEPROM internally organized as 128 words of 8 bits each.
The device complies with the Video Electronics Standard Association's (VESA™), Display Data Channel (DDC™) standards for "Plug-and-Play" monitors.
The "transmitonly" mode (DDC1™) is controlled by the VCLK clock input and the "bi-directional" mode (DDC2™) is controlled by the SCL clock input, with both modes sharing a common SDA input/output (I/O).
CAT24C21 1-kb Dual Mode Serial EEPROM for VESA™ "Plug-and-Play".
