AT88SC0104CA

2. 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.

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.

Note: Does not apply to either the TSSOP or the Ultra Thin Mini-Map pinouts.
