Description
Key Technical Features:
Integrated Storage and Encryption Design
Features 8 Kbit of user storage space, partitioned into 8 independent secure zones. This design supports zone-specific access control and independent key management, thereby enhancing data security.
Each secure zone can be configured with distinct access permissions (Read/Write/Authentication) and supports tamper-resistance and anti-cloning protection.
Hardware-Level Security Mechanisms
Incorporates a built-in CryptoMemory® encryption engine, supporting the 128-bit AES encryption algorithm and a Random Number Generator (RNG) to facilitate secure authentication and encrypted data transmission.
Provides brute-force attack protection: the chip automatically locks down after a threshold of consecutive failed authentication attempts is reached, preventing unauthorised access.
Communication Interface and Compatibility
Utilises an I²C 2-wire serial interface (Standard Mode: 100 kHz; Fast Mode: 400 kHz), facilitating easy integration into a wide range of embedded systems.
Supports the ISO/IEC 7816-3 contact smart card protocol and is compatible with standard smart card readers and writers.
High Reliability and Long Lifespan
Offers an erase/write endurance of up to 100,000 cycles and a data retention period of up to 100 years (under industrial-grade environmental conditions).
Operating temperature range: -25°C to +85°C, making it suitable for use in demanding environments such as industrial, medical, and automotive applications.
Packaging and Environmental Compliance
Commonly available in a DIP8 package, facilitating manual soldering and suitability for small-batch applications.
Compliant with RoHS and REACH environmental standards; classified under ECCN 5A992.c for export control purposes, indicating it is not subject to strict export restrictions.
