1 / 16 page © Semiconductor Components Industries, LLC, 2011 November, 2011 − Rev. 3 1 Publication Order Number: CAT24C512/D 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, MSOP and 8−pad UDFN Packages • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Figure 1.
