AT88SC1616C
Figure 1. Package Options
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.
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.
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.
