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.
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.
SCL and SDA should be fixed to V
