DESCRIPTION

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 "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

C protocol. In write

mode the CAT24C21 features a 16-byte page write

buffer. The device is available in 8-in DIP, SOIC, TSSOP,

MSOP and TDFN packages.
