5. Memory Organization

Atmel AT24C01C, 1K Serial EEPROM: Internally organized with 16 pages of eight bytes each, the 1K requires a 7-bit

data word address for random word addressing.

Atmel AT24C02C, 2K Serial EEPROM: Internally organized with 32 pages of eight bytes each, the 2K requires an 8-bit

data word address for random word addressing.
