CAT24C32
32-Kb I2C CMOS Serial
EEPROM
Description
The CAT24C32 is a 32−Kb CMOS Serial EEPROM devices,
internally organized as 128 pages of 32 bytes each.
It features a 32−byte page write buffer and supports both the
Standard (100 kHz) as well as Fast (400 kHz) I2C protocol.
External address pins make it possible to address up to eight
CAT24C32 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, TDFN and UDFN 8−lead Packages
• This Device is Pb−Free, Halogen Free/BFR Free, and RoHS
Compliant
