1. Description

The AT88SC3216C member of the CryptoMemory® family is a high-performance secure memory providing 32 Kbits of

user memory with advanced security and cryptographic features built in. The user memory is divided into 16 256-byte

zones, each of which may be individually set with different security access rights or effectively combined together to

provide space for 1 to 16 data files.

Smart Card Applications

The AT88SC3216C 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 AT88SC3216C 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.
