With the write command data can be written to the EEPROM. As for this command, set CSB to LOW, then input address
and data after inputting the write ope code. Then, by making CSB HIGH, the EEPROM starts writing. The write time of
EEPROM requires time of tE/W (Max 5ms). During tE/W, commands other than the status read command are not
accepted. Start CSB after taking the last data (D0) and before the next SCK clock starts. At other timings the write
command will not be executed and will be cancelled. The IC has page write functionality. After input 1 byte (8bits) of data,
by continuing data input without starting CSB, data up to 32/64
*1 bytes can be written in one tE/W. In page write, the
insignificant 5/6
*2 bit of the designated address is incremented internally every time 1 byte of data is input, and data is
written to the respective addresses. When data larger then the maximum bytes is input the address rolls over and
previously input data is overwritten.
Write command is executed when CSB rises between the SCK clock rising edge to recognize the 8th bit’s of data input
and the next SCK rising edge. At other timings the write command is not executed and cancelled (Fig.42 valid timing c).
In page write, the CSB valid timing is every 8 bits. If CSB rises at other timings page write is cancelled together with the
write command and the input data is reset.

a:In case of input the data of No.② which is 2 bytes page write command for the data of No.①, EEPROM data changes
like No.③.
b:In case of input the data of No.④ which is 34 bytes page write command for the data of No.①, EEPROM data changes
like No.⑤.
c:In case of a or b, when write command is cancelled, EEPROM data keep No.①.
In page write command, when data is set to the last address of a page (e.g. address “03Fh” of page 1), the next data will be
set to the top address of the same page (e.g. address “020h” of page 1). This is why page write address increment is
available in the same page. As a reference, if of 32 bytes, page write command is executed for 2 bytes the data of the other
30 bytes without addresses will not be changed.
