The EEPROM user memory is divided into 4 zones of 1 Kbits each. Multiple zones allow for stor-
age 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.
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.
