Page Write:

The EEPROM is capable of the page write operation which allows any number of bytes up to 16 bytes to

be written in a single write cycle. The page write is the same sequence as the byte write except for

inputting the more write data. The page write is initiated by a start condition, device address word,

memory address(n) and write data (Dn) with every ninth bit acknowledgment. The EEPROM enters the

page write operation if the EEPROM receives more write data (Dn+1) instead of receiving a stop

condition. The a0 to a3 address bits are automatically incremented upon receiving write data (Dn+1). The

EEPROM can continue to receive write data up to 16 bytes. If the a0 to a3 address bits reaches the last

address of the page, the a0 to a3 address bits will roll over to the first address of the same page and

previous write data will be overwritten. Upon receiving a stop condition, the EEPROM stops receiving

write data and enters internally-timed write cycle.
