DESCRIPTION
The CAT24C01C is a 1K-bit Serial CMOS EEPROM
internally organized as 128 words of 8 bits each. Catalyst鈥檚
advanced CMOS technology substantially reduces de-
vice power requirements. The the CAT24C01C 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 for smartcard micromodule applications.
