DESCRIPTION

TheCAT24FC65/66isa64k-bitSerialCMOSEEPROM

internally organized as 8,192 words of 8 bits each.

Catalyst’s advanced CMOS technology substantially

reduces device power requirements.

The CAT24FC65/66 features a 64-byte page write

buffer. The device operates via the I²C bus serial

interface and is available in 8-pin DIP, SOIC, TSSOP

and TDFN packages.
