CAT24C512 Datasheet, PDF (1/15 Pages) ON Semiconductor – 512 kb I2C CMOS Serial EEPROM 128−Byte Page Write Buffer
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.
Features
• Supports Standard, Fast and Fast−Plus I2C Protocol
• 1.8 V to 5.5 V Supply Voltage Range
• 128−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−pin PDIP, SOIC, TSSOP and 8−pad UDFN Packages
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
