CAT24C128
128 kb I 2 C 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) I 2 C
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.*
