Description

The AT88SC1616C member of the CryptoMemory

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.

2.

Smart Card Applications

The AT88SC1616C 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 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 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 AT88SC1616C is available

in industry standard 8-lead packages with the same familiar pinout as 2-wire serial EEPROMs.
