Smart Card Applications
The AT88SC0104CA provides high security, low cost, and ease of implementation without the need for a
microprocessor operating system. The embedded cryptographic engine provides for dynamic, 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
AT88SC0104CA 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, symmetric-mutual authentication, data encryption, and the use of cryptographic Message
Authentication Codes (MAC), the AT88SC0104CA 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 speeds up to 1.0 MHz provides fast and efficient communications with up to 15 individually addressable
devices. The AT88SC0104CA is available in industry standard 8-lead packages with the same familiar pin configuration
as AT24CXXX serial EEPROM devices.
