DESCRIPTION  
The CAT24WC03/05 is a 2K/4K-bit Serial CMOS  
EEPROM internally organized as 256/512 words of 8  
bits each. Catalyst’s advanced CMOS technology sub-  
stantially reduces device power requirements. The  
CAT24WC03/05 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 or 8-pin SOIC packages.
