2. Description

The AT88SC0104CA member of the CryptoMemory® family is a high-performance secure mem-

ory providing 1 Kbit of user memory with advanced security and cryptographic features built in.

The user memory is divided into four 32-byte zones, each of which may be individually set with

different security access rights or effectively combined together to provide space for 1 to 4 data

files. The AT88SC0104CA features an enhanced command set that allows direct communica-

tion with microcontroller hardware 2-Wire interface thereby allowing for faster firmware

development with reduced code space requirements.

3. 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 (Gem-

plus Patent) defined in ISO 7816-3.

4. Embedded Applications

Through dynamic, symmetric-mutual authentication, data encryption, and the use of crypto-

graphic Message Authentication Codes (MAC), the AT88SC0104CA 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

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 TSSOP pinout.
