6. Write
6.1Byte Write
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code “0”,
following the start condition signal, it outputs the acknowledgment signal. Next, when the EEPROM receives an
8-bit length word address, it outputs the acknowledgment signal.
After the EEPROM receives 8-bit write data and outputs the acknowledgment signal, it receives the stop
condition signal. Next, the EEPROM at the specified memory address starts to rewrite.
When the EEPROM is rewriting, all operations are prohibited and the acknowledgment signal is not output.
6.2Page Write
Up to 8 bytes per page can be written in the S-24C01B and S-24C02B.
Up to 16 bytes per page can be written in the S-24C04B.
Basic data transmission procedures are the same as those in the “Byte Write”. However, when the EEPROM
receives 8-bit write data which corresponds to the page size, the page can be written.
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code “0”,
following the start condition signal, it outputs the acknowledgment signal. When the EEPROM receives an 8-bit
length word address, it outputs the acknowledgment signal.
After the EEPROM receives 8-bit write data and outputs the acknowledgment signal, it receives 8-bit write
data corresponding to the next word address, and outputs the acknowledgment signal. The EEPROM repeats
reception of 8-bit write data and output of the acknowledgment signal in succession. It is capable of receiving
write data corresponding to the maximum page size.
When the EEPROM receives the stop condition signal, it starts to rewrite, corresponding to the size of the
page, on which write data, starting from the specified memory address, is received.
