17.5.2 Write/Erase Endurance
The endurance is 10⁵ cycles/page (1% cumulative failure rate) in case of page programming and
10⁴ cycles/byte in case of byte programming. The data retention time is more than 10 years when a
device is page-programmed less than 10⁴ cycles.
17.5.3 Noise Suppression Time
This EEPROM has a noise suppression function at SCL and SDA inputs, that cuts noise of width
less than 50 ns. Be careful not to allow noise of width more than 50 ns because the noise of with
more than 50 ms is recognized as an active pulse.
