1. Description
The AT88SC12816C member of the CryptoMemory^® family is a high-performance secure memory providing 128 Kbits
of user memory with advanced security and cryptographic features built in. The user memory is divided into 16 1-Kbyte
zones, each of which may be individually set with different security access rights or effectively combined together to
provide space for one to sixteen data files.

Smart Card Applications
The AT88SC12816C provides high security, low cost, and ease of implementation without the need for a
microprocessor operating system. The embedded cryptographic engine provides for dynamic and symmetric mutual
authentication between the device and host, as well as performing stream encryption for all data and passwords
exchanged between the device and host. Up to four unique key sets may be used for these operations. The
AT88SC12816C offers the ability to communicate with virtually any smart card reader using the asynchronous T = 0
protocol (Gemplus Patent) defined in ISO 7816-3. Communication speeds up to 153,600 baud are supported by
utilizing ISO 7816-3 Protocol and Parameter Selection.
