Description

The AT88SC1616C member of the CryptoMemory

memory providing 16 Kbits of user memory with advanced security and cryptographic

features built in. The user memory is divided into 16 128-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 AT88SC1616C provides high security, low cost, and ease of implementation with-

out 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 AT88SC1616C offers the ability to communicate with virtually any

smart card reader using the asynchronous T = 0 protocol (Gemplus patent) defined in

ISO 7816-3.

Embedded Applications

Through dynamic and symmetric mutual authentication, data encryption, and the use of

encrypted checksums, the AT88SC1616C provides a secure place for storage of sensi-

tive 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 AT88SC1616C is available in industry standard 8-lead packages with

the same familiar pinout as 2-wire serial EEPROMs.
