2. Description
Atmel^® AT88SCxxxxC is a family of nine high-performance secure memory devices providing 1-Kbit to 256-Kbit of user
memory with advanced built-in security and cryptographic features. The memory 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 effectively provide space for one or
multiple data files. Atmel CryptoMemory^® has a configuration memory which 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.
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 cryptographic 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.
2.1 Embedded Applications
A 2-Wire serial interface running at 1MHz is used for fast and efficient communications with up to 15 devices which can be
individually addressed. CryptoMemory is available in industry standard 8-lead packages with the same familiar pinout as
2-Wire Serial EEPROMs supporting only the synchronous communications protocol.
