DESCRIPTION
The CAT24FC02 is a 2-kb Serial CMOS EEPROM
internally organized as 256 words of 8 bits each. Catalyst鈥檚
advanced CMOS technology substantially reduces
device power requirements.
The CAT24FC02 features a 16-byte page write buffer.
The device operates via the I
2
C bus serial interface and
is available in 8-pin DIP, SOIC, TSSOP and MSOP
packages.
