CAT24C64

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 (SCL and SDA) Low Power CMOS Technology 1,000,000 Program/Erase Cycles 100 Year Data Retention Industrial and Extended Temperature Range SOIC, TSSOP, UDFN 8−pad and Ultra−thin WLCSP 4−bump Packages This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant VCC SCL A2, A1, A0 WP CAT24C64 SDA VSS Figure 1.
