DESCRIPTION

The CAT24WC66 is a 64K-bit Serial CMOS EEPROM

internally organized as 8192 words of 8 bits each.

Catalyst’s advanced CMOS technology substantially

reduces device power requirements. The

CAT24WC66 features a 32-byte page write buffer. The

device operates via the I

C bus serial interface and is

available in 8-pin DIP or 8-pin SOIC packages.
