DESCRIPTION
The CAT24FC65/66 is a 64k-bit Serial CMOS EEPROM
internally organized as 8,192 words of 8 bits each.
Catalyst鈥檚 advanced CMOS technology substantially
reduces device power requirements.
The CAT24FC65/66 features a 64-byte page write
buffer. The device operates via the I
2
C bus serial
interface and is available in 8-pin DIP, SOIC, TSSOP
and TDFN packages.
