Application

The AT88SC0204C provides high security, low cost, and ease of implementation without the need for a micropro-cessor operating system. The embedded cryptographic engine provides for dynamic, symmetricmutual authen-tication between the device and host, as well as performing stream encryption for all data and passwords exchan-ged between the device and host. Up to four unique key sets may be used for these operations. The AT88SC0204C offers the ability to communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gemplus Patent) defined in ISO 7816-3.

Description

The AT88SC0204C member of the CryptoMemory family is a high-performance secure memory providing 2 Kbits of user memory with advanced security and cryptographic features built in. The user memory is divided into four 64-byte zones, each of which may be individually set with different security access rights or combined together to provide space for 1 to 4 data files.
