• One of a Family of Devices with User Memories from 1 Kbit to 1 Mbit
• 1-Kbit (128-byte) EEPROM User Memory
Four 32 byte (256 bit) Zones
Self-timed Write Cycle (5 ms)
Single Byte or 16-byte Page Write Mode
Programmable Access Rights for Each Zone
• 2-Kbit Configuration Zone
37-byte OTP Area for User-defined Codes
160-byte Area for User-defined Keys and Passwords
• High Security Features
64-bit Patented Dynamic Symetric Mutual Authentication Protocol (Under Exclusive Patent License from ELVA)
Encrypted Checksum
Stream Encryption
Four Key Sets for Authentication and Encryption
Eight Sets of Two 24-bit Passwords
Anti-tearing Function
Voltage and Frequency Monitor
• Smart Card Features
ISO 7816 Class A (5V) or Class B (3V) Operation
ISO 7816-3 Asynchronous T = 0 Protocol (Gemplus Patent)
Multiple Zones, Key Sets and Passwords for Multi-application Use
Synchronous 2-wire Serial Interface for Faster Device Initialization
Programmable 8-byte Answer-To-Reset Register

ESD Protection: 4,000V min

AT88SC0104C Typical Application

Smart Card Applications 
The AT88SC0104C provides high security, low cost, and ease of implementation without the need for a micropro-cessor operating system. The embedded cryptographic engine provides for dynamic, symmetric-mutual authenti-cation between the device and host, as well as performing stream encryption for all data and passwords exchan-ged between the device and host. Up to four unique key sets may be used for these operations. The AT88SC0104C 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 encrypted checksums, the AT88SC0104C 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 1.5 MHz is used for fast and efficient communications with up to 15 devices that may be individually addressed. The AT88SC0104C is available in industry standard 8-lead packages with the same familiar pinout as 2-wire serial EEPROMs.
