CAT24C21  
1 kb Dual Mode Serial  
EEPROM for VESAt  
“Plug-and-Play”  
Description  
http://onsemi.com  
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 “PlugandPlay” monitors. The  
“transmitonly” mode (DDC1) is controlled by the VCLK clock  
input and the “bidirectional” mode (DDC2) is controlled by the  
SCL clock input, with both modes sharing a common SDA  
input/output (I/O). The transmitonly mode is a readonly mode,  
while the bidirectional mode is a read and write mode following the
