DESCRIPTION

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 2K-bit Serial CMOS EEPROM

internallyorganizedas256wordsof8bitseach.Catalyst’s

advanced CMOS technology substantially reduces de-

vice power requirements. The CAT34WC02 features a
