... DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are hard wired for the AT24C01B. As many as eight 1K devices may be addressed on a sin- gle bus system (device addressing is discussed in detail under the Device Addressing section). WRITE PROTECT (WP): The AT24C01B has a write protect pin that provides hardware data protection ...

... The data word address lower three bits are internally incremented following the receipt of each data word. The higher data word address bits are not incremented, retaining the memory page row location. When the word address, internally generated, reaches the page boundary, the fol- lowing byte is placed at the beginning of the same page. If more than eight data words are transmitted to the EEPROM, the data word address will “ ...
