DESCRIPTION
The CAT24C02C is a 2K-bit Serial CMOS E
2
PROM
internally organized as 256 words of 8 bits each. Catalyst鈥檚
advanced CMOS technology substantially reduces de-
vice power requirements. The the CAT24C02C features
a 16-byte page write buffer. The device operates via the
I
2
C bus serial interface and has a ISO 7816 compatible
pinout.
