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.
1.1. 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.

1.2. Embedded Applications
Through dynamic and symmetric mutual authentication, data encryption, and the use of encrypted checksums, the
AT88SC3216C provides a secure place for storage of sensitive information within a system. With its tamper detection
circuits, this information remains safe even under attack. A 2-wire serial interface running at 1.0 MHz is used for fast
and efficient communications with up to 15 devices that may be individually addressed. The AT88SC3216C is available
in industry standard 8-lead packages with the same familiar pinout as 2-wire serial EEPROMs.
