2. Description
The AT88SCxxxxC is a family of 9 high-performance secure memory devices providing 1K to
256K bits of user memory with advanced built-in security and cryptographic features. The mem-
ory is divided into 4, 8 or 16 user zones each of which may be individually set with different
security access rights or used together to provide space for one or multiple data files. Cryptom-
emory has a configuration memory that contains registers to define the security rights for each
user zone and space for passwords and secret keys used by the security logic of
CryptoMemory.
Through dynamic, symmetric mutual authentication, data encryption, and the use of encrypted
checksums, CryptoMemory provides a secure place for storage of sensitive information within a
system. With its tamper protection circuits, this information remains safe even under attack.
5210B–SMIC–11/08
CryptoMemory also provides high security, low cost and ease of implementation of host-client
type systems without the need for a microprocessor operating system. The embedded crypto-
graphic engine provides for a dynamic, symmetric mutual authentication between the device and
host, as well as performs stream encryption for all data and passwords exchanged between the
device and host. Up to four unique key sets are available for these operations.
