Device Architecture
User Zones
The EEPROM user memory is divided into 16 zones of 1024 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 the user 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 5-1. User Zones
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.
