CAT24C21
1 kb Dual Mode Serial
EEPROM for VESA t
“Plug-and-Play”
Description
The CAT24C21 is a 1 kb Serial CMOS EEPROM internally
organized as 128 words of 8 bits each. The device complies with the
http://onsemi.com
Video Electronics Standard Association’s (VESA ? ), Display Data
Channel (DDC ? ) standards for “Plug ? and ? Play” monitors. The
“transmit ? only” 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). The transmit ? only mode is a read ? only mode,

while the bi ? directional mode is a read and write mode following the
I 2 C protocol. In write mode the CAT24C21 features a 16 ? byte page
write buffer. The device is available in 8 ? lead DIP, SOIC, TSSOP,
MSOP and TDFN packages.
