CAT24C512 2 EEPROM Serial 512-Kb I C Description 2 The CAT24C512 is a EERPOM Serial 512Kb I C internally organized as 65,536 words of 8 bits each. It features a 128byte page write buffer and supports the Standard 2 (100 kHz), Fast (400 kHz) and FastPlus (1 MHz) I C protocol. www.onsemi.com 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. UDFN8 TSSOP8 SOIC8 OnChip ECC (Error Correction Code) makes the device suitable HU5 SUFFIX Y SUFFIX X SUFFIX for high reliability applications.
