DESCRIPTION

The CAT24WC01/02/04/08/16 is a 1K/2K/4K/8K/16K-

bit Serial CMOS E

PROM internally organized as 128/

256/512/1024/2048 words of 8 bits each. Catalyst’s

advanced CMOS technology substantially reduces de-

vice power requirements. The the CAT24WC01/02/04/

08/16 feature 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, 8-

pin SOIC or 8-pin TSSOP.
