AT88SC0808CA
Smart Card Module
The AT88SC0808CA member of the CryptoMemory® family is a high-performance secure
memory providing 8 Kbit of user memory with advanced security and cryptographic features built
in. The user memory is divided into eight 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 8
data files. The AT88SC0808CA features an enhanced command set that allows direct communi-
cation with microcontroller hardware 2-Wire interface thereby allowing for faster firmware
development with reduced code space requirements.
The AT88SC0808CA 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 AT88SC0808CA offers the ability to
communicate with virtually any smart card reader using the asynchronous T = 0 protocol (Gem-
plus Patent) defined in ISO 7816-3.
Through dynamic, symmetric-mutual authentication, data encryption, and the use of crypto-
graphic Message Authentication Codes (MAC), the AT88SC0808CA provides a secure place for
storage of sensitive information within a system. With its tamper detection circuits, this informa-
tion 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
AT88SC0808CA is available in industry standard 8-lead packages with the same familiar pin
configuration as AT24CXXX serial EEPROM devices.
