User Memory
The EEPROM user memory is divided into four (AT88SC0104CA/0204CA/0404CA) or eight (AT88SC0808CA) user zones.
Multiple zones allow for the storage of different data types or files in different zones. Access to user zones is possible only
after meeting security requirements. The customer defines these security requirements in the configuration zone during device
personalization. When the same security requirements define access to multiple zones, the zones effectively serve as one
large storage area albeit with the requirement to select each zone prior to access. User zone access is personalized by
customer via the access registers.
