EEPROM has 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

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.
