• Manufacturer Part Number: le24l042cs
• Description: Wire Serial Interface Eeprom
• Manufacturer: Sanyo Semiconductor Corporation

Functional Description
1 Start condition
2 Stop condition
3 Data transfer
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.
