DESCRIPTION

The CAT24C21 is a 1k-bit Serial CMOS EEPROM

internally organized as 128 words of 8 bits each. The

CAT24C21 can operate in two modes compliant to the

VESA™, DDC1™ and DDC2™ standards for "Plug-

and- Play" monitors. The Transmit-only Mode controlled

by the VCLK input and the bi-directional Mode where the

memories content is controlled by the I

C bus, SCL

input. Catalyst’s advanced CMOS technology

substantially reduces device power requirements. The

CAT24C21 features a 16-byte page write buffer. The

device operates via the I

C bus serial interface, has a

special write protection feature, and is available in 8-pin

DIP, SOIC, TSSOP and MSOP packages.
