64kb I2C CMOS Serial EEPROM
Description
64 Kb I2C CMOS Serial EEPROM
CAT24C64
Description
The CAT24C64 is a 64 Kb CMOS Serial EEPROM device, internally organized as 8192 words of 8 bits each.
It features a 32−byte page write buffer and supports the Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I2C protocol.
External address pins make it possible to address up to eight CAT24C64 devices on the same bus.
Features
• Supports Standard, Fast and Fast−Plus I2C Protocol • 1.
7 V to 5.
5 V Supply Voltage Range • 32−Byte Page Write Buffer • Hardware Write Protection for Entire Memory • Schmitt Triggers and Noise Suppression Filters on I2C Bus Inputs
