Maxim Integrated DS28E01PMOD+ Secure Authenticator

The DS28E01PMOD+ is a highly secure, single-chip solution provided by Maxim Integrated that combines 1024 bits of user-programmable EEPROM with a unique, factory-programmed 64-bit registration number. This secure authenticator is designed for applications where the protection of sensitive data and the authentication of components are critical, such as in supply chain management, after-market protection, and in the safeguarding of intellectual property and revenue streams.

Key Features

• High-Security Authentication: The chip integrates the secure SHA-1 algorithm, ensuring robust protection against unauthorized access and counterfeit products.
• Unique Serial Number: Each DS28E01PMOD+ contains a unique 64-bit ROM identification number, which is factory programmed to provide a strong foundation for the creation of a secure authentication system.
• User-Programmable EEPROM: The 1024 bits of EEPROM can be used to store secure data such as cryptographic keys, configurable settings, or other sensitive information.
• Write Protection: EEPROM segments can be permanently write-protected or put in EPROM-emulation mode, where data becomes write-once read-many (WORM), enhancing the security of the data.
• Challenge-Response Authentication: The device supports a challenge-response authentication scheme, using the SHA-1 algorithm to verify the authenticity of a product or component.
• Single Contact Interface: Communication with the DS28E01PMOD+ is achieved through the 1-Wire interface, which requires only a single data lead and a ground return.

Applications

• Secure Data Storage
• Medical and Healthcare Device Authentication
• Peripheral Authentication
• Supply Chain Integrity and Brand Protection
• After-market Safety and Warranty Protection

The DS28E01PMOD+ is a versatile and reliable choice for designers who need a tamper-resistant authentication system. Its small form factor, combined with low-power operation and minimal external component requirements, makes it an ideal choice for a wide range of applications. By incorporating the DS28E01PMOD+ into your design, you can ensure the integrity and security of your products, protect your brand, and safeguard your revenue from counterfeit goods.
