CAT24C512
512 Kb I2C CMOS Serial
EEPROM
Description
The CAT24C512 is a 512 Kb Serial CMOS EEPROM, internally
organized as 65,536 words of 8 bits each.
www.onsemi.com
It features a 128−byte page write buffer and supports the Standard
2
(100 kHz), Fast (400 kHz) and Fast−Plus (1 MHz) I C 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
CAT24C512 devices on the same bus.
On−Chip ECC (Error Correction Code) makes the device suitable
for high reliability applications.
