Maxim Integrated DS2431X-S+ Secure Silicon Serial Number

The Maxim Integrated DS2431X-S+ is a highly secure, low-cost, silicon-based serial number chip that provides a unique identity to hardware devices. This chip comes in a compact, six-pin TSOC package, making it suitable for a wide range of applications including accessory identification, device authentication, and asset tracking.

Key Features:

• Secure Unique ID: Each DS2431X-S+ chip contains a factory-lasered, 64-bit ROM ID that is unique to each device, ensuring no two chips share the same number. This feature is crucial for preventing counterfeiting and ensuring secure device authentication.
• SHA-1 Engine: Equipped with a built-in, FIPS 180-3 specified Secure Hash Algorithm (SHA-1) engine, the DS2431X-S+ offers robust data integrity and authentication capabilities.
• Memory: The device includes a 1024-bit, user-programmable EEPROM, partitioned into four 256-bit pages. The EEPROM can be used for storing sensitive data, which is protected by the SHA-1 engine to prevent unauthorized access or tampering.
• Challenge-and-Response Authentication: The DS2431X-S+ supports a challenge-and-response authentication scheme, which uses the SHA-1 engine to validate the authenticity of the device and its data.
• Durability: The chip is designed to withstand harsh environments and is rated for operation across the -40°C to +85°C temperature range, making it suitable for industrial and outdoor applications.

Applications:

• PCB and System Identification
• Medical Device Authentication
• Supply Chain Management
• Aftermarket and Customer Management
• Accessory and Peripheral Authentication

By integrating the DS2431X-S+ into your product, you can ensure a high level of security and prevent unauthorized duplication, thereby protecting your brand and intellectual property. Its small size and powerful security features make it an indispensable component for any application where secure identification and data integrity are of paramount importance.
