CAV24C256
256-Kb I2C CMOS Serial
EEPROM
Description
The CAV24C256 is a 256−Kb Serial CMOS EEPROM, internally
organized as 32,768 words of 8 bits each.
It features a 64−byte page write buffer and supports 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).
External address pins make it possible to address up to eight
CAV24C256 devices on the same bus.
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.
