DESCRIPTION

a 16-byte page write buffer. The device operates via the

I²C bus serial interface and is available in 8-pin DIP,

8-pin SOIC or 8-pin TSSOP packages.

The CAT34WC02 is a 2-kb Serial CMOS EEPROM

internallyorganizedas256wordsof8bitseach.Catalyst’s

advanced CMOS technology substantially reduces

device power requirements. The CAT34WC02 features
