CMOS Serial EEPROMs
onsemi offers CMOS Serial EEPROMs with various memory configurations. The CAT24C512 is a 512 kb Serial CMOS EEPROM, internally organized as 65,536 words of 8 bits each. The CAT24M01 is a 1024 kb CMOS Serial EEPROM, internally organized as 131,072 words of 8 bits each. They feature a 128-byte (CAT24C512) page or 256-byte (CAT24M01) write buffer and support 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) or four (CAT24M01) devices on the same bus.
