CAT24C64 Datasheet | Catalyst Semiconductor

Features 64-Kb I2C CMOS Serial EEPROM DEVICE DESCRIPTION The CAT24C64 is a 64-Kb CMOS Serial EEPROM devices, internally organized as 128 pages of 64 bytes each. It Features a 32-byte page write buffer and supports both the Standard (100 k Hz) as well as Fast (400 k Hz) I2C protocol. External address pins make it possible to address up to eight CAT24C64 devices on the same bus. - Supports Standard and Fast I2C Protocol - 1.8 V to 5.5 V Supply Voltage Range - 32-Byte Page Write Buffer(1) - Hardware Write Protection for entire memory - Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs (SCL and SDA). - Low power CMOS technology - 1,000,000 program/erase cycles - 100 year data retention - Industrial temperature range - Ro HS-pliant 8-pin PDIP, SOIC, TSSOP and TDFN packages Note: (1) CAT24C64 Rev. D (Not Remended for New Designs) has 64-Byte Page Write Buffer. .. For Ordering Information details, see page 15.
