CAT24C512

EEPROM Serial 512-Kb I2C CAT24C512 Description The CAT24C512 is a EERPOM Serial 512−Kb I2C 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.
