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.

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.
