The Data bytes 0 to 31 can be protected against further changes by programming the associated
protection bit 0 to 31. The SLE 4442 allows data changing only after correct verification of the
Reference Data bytes. Reading of the Data bytes and of the associated protection bits is always
possible.

damage to the device. This is a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the operational sections of this data
sheet is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability, including EEPROM data retention and write/erase endurance.
In the operating range the functions given in the circuit description are fulfilled.
