Control Logic

Configuration

Memory

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.

The configuration memory consists of 2048 bits of EEPROM memory used for storing pass-

words, keys and codes and defining security levels to be used for each user zone. Access rights

to the configuration memory are defined in the control logic and may not be altered by the user.
