DESCRIPTION
The CAT24WC03/05/09/17 is a 2K/4K/8K/16K-bit Serial
CMOS E
2
PROM internally organized as 256/512/1024/
2048 words of 8 bits each. Catalyst’s advanced CMOS
technology substantially reduces device power require-
ments. The CAT24WC03/05/09/17 features a 16-byte
page write buffer. The device operates via the I
2
C bus
serial interface, has a special write protection feature,
and is available in 8-pin DIP or 8-pin SOIC
