Notes
Data Protection at V
When V
may act as a trigger and turn the EEPROM to unintentional program mode. To prevent this unintentional
programming, this EEPROM have a power on reset function. Be careful of the notices described below in
order for the power on reset function to operate correctly.
• SCL and SDA should be fixed to V
• V
• V
Write/Erase Endurance and Data Retention Time
The endurance is 10
cumulative failure rate). The data retention time is more than 10 years when a device is page-programmed
less than 10
Noise Suppression Time
This EEPROM have a noise suppression function at SCL and SDA inputs, that cut noise of width less than
50 ns. Be careful not to allow noise of width more than 50 ns.
