User Zones

The EEPROM user memory is divided into 16 zones of 16,384 bits each. Multiple zones allow

for different types of data or files to be stored in different zones. Access to the user zones is

allowed only after security requirements have been met. These security requirements are

defined by the user during the personalization of the device in the configuration memory. If the

same security requirements are selected for multiple zones, then these zones may effectively be

accessed as one larger zone.
