Functional Description
1 Start condition
2 Stop condition
3 Data transfer
4 Acknowledge
Data is transferred by changing the SDA line while the SCL line is low. When the SDA line is changed while the SCL
line is high, the resulting condition will be recognized as the start or stop condition.
When the SCL line is at the high level, the start condition is established by changing the SDA line from high to low.
The operation of the EEPROM as a slave starts in the start condition.
When the SCL line is at the high level, the stop condition is established by changing the SDA line from low to high.
When the device is set up for the read sequence, the read operation is suspended when the stop condition is received,
and the device is set to standby mode. When it is set up for the write sequence, the capture of the write data is ended
when the stop condition is received, and the EEPROM internal write operation is started.
SCL
SDA
During data transfer, 8-bits are transferred in succession, and then in the ninth clock cycle period the device on the
system bus receiving the data sets the SDA line to low, and sends the acknowledge signal indicating that the data has
been received. The acknowledge signal is not sent during an EEPROM internal write operation.
