CAT24C128
128 kb I²C CMOS Serial
EEPROM
Description
The CAT24C128 is a 128 kb Serial CMOS EEPROM, internally
organized as 16,384 words of 8 bits each.
It features a 64−byte page write buffer and supports both the
Standard (100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I²C
protocol.
Write operations can be inhibited by taking the WP pin High (this
protects the entire memory).
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.*
Features
• Supports Standard, Fast and Fast−Plus I²C Protocol
• 1.8 V to 5.5 V Supply Voltage Range
• 64−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
• 8−lead PDIP, SOIC, TSSOP, MSOP and UDFN Packages
• This Device is Pb−Free, Halogen Free/BFR Free and RoHS
Compliant**
