Overview

High-performance secure memory that provides 8Kbit 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 either individually set with different security access rights or effectively combined together to provide space for one to eight data files.

• One of a Family of 9 Devices with User Memories from 1 Kbit to 256-Kbit• 8-Kbit (1-Kbyte) EEPROM User Memory – Eight 128-byte (1-Kbit) Zones – Self-timed Write Cycle – 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 – 64-bit Mutual Authentication Protocol (Under License of 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 – 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 – ISO 7816-2 Compliant Modules• Embedded Application – Low Voltage Operation: 2.7V to 5.5V – Secure Nonvolatile Storage for Sensitive System or User Information – 2-wire Serial Interface – 1.0 MHz Compatibility for Fast Operation – Standard 8-lead Plastic Packages – Same Pinout as 2-wire Serial EEPROMs• High Reliability – Endurance: 100,000 Cycles – Data Retention: 10 years – ESD Protection: 4,000V min
