DESCRIPTION
The CAT24FC65/66 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 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.
