8. Device Architecture

8.1 User Zones

The EEPROM user memory is divided into 4 zones of 256 bits each. Multiple zones allow for

storage of different types of data or files in different zones. Access to user zones is permitted

only after meeting proper security requirements. These security requirements are user definable

in the configuration memory during device personalization. If the same security requirements are

selected for multiple zones, then these zones may effectively be accessed as one larger zone.
