Device Architecture
User Zones
The EEPROM user memory is divided into 16 zones of 8,192 bits each. Multiple zones allow for different types of data
or files to be stored in different zones. Access to the user zones is allowed only after security requirements have been
met. These security requirements are defined by theuser during the personalization of the device in the configuration
memory. If the same security requirements are selected for multiple zones, then these zones may effectively be
accessed as one larger zone.
Figure 8.
Control Logic
Access to the user zones occurs 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.
