DESCRIPTION  
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 I2C bus serial interface, has a  
special write protection feature, and is available in 8-pin  
DIP, SOIC, TSSOP and MSOP packages.  
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. TheTransmit-onlyModecontrolled  
bytheVCLKinputandthebi-directionalModewherethe  
memories content is controlled by the I2C bus, SCL
