DESCRIPTION
The CAT24FC01 is a 1-kb Serial CMOS EEPROM
internally organized as 128 words of 8 bits each. Catalyst’s
advanced CMOS technology substantially reduces
device power requirements.
The CAT24FC01 features a 16-byte page write buffer.
The device operates via the I²C bus serial interface and
is available in 8-pin DIP, 8-pin SOIC, 8-pin TSSOP and
MSOP packages.
