1 / 10 page © 2005 by Catalyst Semiconductor, Inc. Characteristics subject to change without notice 1 CAT24FC65, CAT24FC66 64K-Bit I2C Serial CMOS EEPROM with Partial Array Write Protection Doc. No. 1047, Rev. H PIN FUNCTIONS Pin Name Function A0, A1, A2 Address Inputs SDA Serial Data/Address SCL Serial Clock WP Write Protect VCC +2.5V to +5.5V Power Supply VSS Ground NC No Connect 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. * Catalyst Semiconductor is licensed by Philips Corporation to carry the I2C Bus Protocol. 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.
