User Memory
The EEPROM user memory is divided into four (Atmel
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.
