The Maxim Integrated DS2460S+T is a versatile and secure SHA-1 coprocessor that provides a robust solution for data authentication and data encryption tasks. This compact device is designed to add an extra layer of security to various applications, including accessory authentication, consumable authentication, and embedded security systems.

Key Features

• SHA-1 Engine: At the heart of the DS2460S+T is a high-performance Secure Hash Algorithm 1 (SHA-1) engine that ensures the integrity of data through the creation of a 160-bit hash from the input data.
• One-Wire Interface: The device utilizes Maxim's exclusive One-Wire interface, which allows communication through a single data line plus ground for simplified connectivity, thereby reducing the wiring complexity and the overall cost of the system.
• EEPROM Storage: It comes with 512 bits of user EEPROM partitioned into four pages where data can be read and written. Additionally, it includes a 64-bit secret, a 64-bit register for the secret, and a 64-bit ROM ID unique to each device.
• Flexible User Memory: The user-accessible EEPROM can be used to store data that can be read and written through the One-Wire interface, providing a versatile storage solution.
• Secure Authentication: The DS2460S+T is capable of generating and verifying Message Authentication Codes (MACs), enabling the creation of a secure authentication system to prevent unauthorized access to data.

Applications

The DS2460S+T is ideal for a wide range of applications where data security is paramount. It is commonly used in:

• Accessory and consumable authentication
• Embedded security systems
• Medical device authentication
• Aftermarket product protection
• Secure data storage and transmission

Technical Specifications

The device operates over a wide voltage range of 2.9V to 5.5V and is specified for operation over the full industrial temperature range (-40°C to +85°C). The DS2460S+T is available in a compact, surface-mountable 6-pin TSOC package, making it suitable for space-constrained applications.

With its robust security features and convenient One-Wire interface, the Maxim Integrated DS2460S+T is an excellent choice for designers looking to enhance the security of their systems with minimal overhead and complexity.
