Initial Device Programming
Enabling the security features of CryptoMemory requires prior personalization. Personalization entails setting up of desired
access rights by zones, passwords and key values, programming these values into the configuration memory with verification
using simple write and read commands, and then blowing fuses to lock this information in place.
Gaining access to the configuration memory requires successful presentation of a secure (or transport) code. The initial
signature of the secure (transport) code for the AT88SC0104CA device is $DD 42 97. This is the same as the write seven
password. The user may elect to change the signature of the secure code anytime after successful presentation.
After writing and verifying data in the configuration memory, the security fuses must be blown to lock this information in the
device. For additional information on personalizing CryptoMemory, please see the application notes Programming
CryptoMemory for Embedded Applications and Initializing CryptoMemory for Smart Card Applications from the product page at
www.atmel.com/products/securemem.
