a _DESCRIPTION
The CAT24FC64 is a 64K-bit Serial CMOS EEPROM
P _{internally organized as 8,192 words of 8 bits each.}
Catalyst’s advanced CMOS technology substantially
reduces device power requirements. The CAT24FC64
features a 64-byte page write buffer. The device oper-
ates via the I²C bus serial interface and is available in 8-
pin DIP, SOIC, TSSOP and TDFN packages.
