Write Operations
Byte Write:
A write operation requires an 8-bit device address word with R/W = “0”. Then the EEPROM sends
acknowledgment "0" at the ninth clock cycle. After these, EEPROMs receive 8-bit memory address word.
Upon receipt of this memory address, the EEPROM outputs acknowledgment "0" and receives a following
8-bit write data. After receipt of write data, the EEPROM outputs acknowledgment "0". If the EEPROM
receives a stop condition, the EEPROM enters an internally-timed write cycle and terminates receipt of
SCL, SDA inputs until completion of the write cycle. The EEPROM returns to a standby mode after
completion of the write cycle.

Page Write:
The EEPROM is capable of the page write operation which allows any number of bytes up to 8 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
a2 address bits are automatically incremented upon receiving write data(Dn+1). The EEPROM can
continue to receive write data up to 8 bytes. If the a0 to a2 address bits reaches the last address of the page,
the a0 to a2 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.
