Device Architecture
User Zones
The EEPROM user memory is divided into 8 zones of 1 Kbits 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.
Figure 9.
Control Logic
Access to the user zones occur only through the control logic built into the device. This logic is configurable through
access registers, key registers and keys programmed into the configuration memory during device personalization.
Also implemented in the control logic is a cryptographic engine for performing the various higher-level security
functions of the device.
