Detailed Description
To enable the security features of Atmel
appropriate passwords and keys. Do these by programming the configuration memory using simple write and read
commands. Gain access to the configuration memory by successfully presenting the secure code (Write 7 password).
After writing and verifying data in the configuration memory, blow the security fuses to lock this information in the
device. For additional information on personalizing CryptoMemory, please see the
this specification
User Memory
The EEPROM user memory is divided into 4, 8 or 16 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 memory 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. Table 2 through Table 10 presents the memory map of
the user zones for the different device densities.
