DESCRIPTION
The CAT24FC64 is a 64K-bit Serial CMOS EEPROM
internally organized as 8,192 words of 8 bits each.
Catalyst’s advanced CMOS technology substantially
reduces device power requirements. The CAT24FC64
* Catalyst Semiconductor is licensed by Philips Corporation to carry the I2C Bus Protocol.
features a 64-byte page write buffer. The device oper-
ates via the I2C bus serial interface and is available in 8-
pin DIP or 8-pin SOIC packages.
