CAT24C512_15 Datasheet, PDF (1/17 Pages) ON Semiconductor – 512 Kb I2C CMOS Serial EEPROM

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.
It features a 128−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
CAT24C512 devices on the same bus.
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
