CAT24C64_16 Datasheet, PDF (1/16 Pages) ON Semiconductor – 64 Kb I2C CMOS Serial EEPROM

CAT24C64
64 Kb I²C CMOS Serial
EEPROM
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
• PDIP, SOIC, TSSOP, US 8−lead, UDFN 8−pad and Ultra−thin
WLCSP 4−bump Packages
• This Device is Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant
