Maxim Integrated DS28E01-100+ Secure Authenticator

The DS28E01-100+ is a highly secure, SHA-1-based authenticator component from Maxim Integrated that provides a robust defense against unauthorized usage and cloning for a variety of applications. This advanced security device combines a large user-programmable EEPROM with a dedicated hardware-based security system to ensure the integrity and security of the data.

At the heart of the DS28E01-100+ is a 1024-bit one-time programmable (OTP) EPROM partitioned into four pages of 256 bits. This memory can be used to store sensitive data, such as cryptographic keys, which are crucial for the device's security functions. The inclusion of a unique, factory-programmed 64-bit registration number ensures that each DS28E01-100+ device is unique, which is essential for traceability and protection against counterfeiting.

The device features a challenge-and-response security scheme based on the FIPS180-3 specified Secure Hash Algorithm (SHA-1). With this system, the DS28E01-100+ can generate high-security, 160-bit Message Authentication Codes (MACs) that prove the authenticity of the device and its data. This makes the DS28E01-100+ an ideal choice for safeguarding network data, preventing the use of counterfeit products, and ensuring secure access to sensitive systems.

Operating over the 1-Wire® bus, the DS28E01-100+ requires just a single contact for communication and can derive power directly from the data line ('parasite power'), minimizing the need for additional power supplies. This simplifies integration into existing systems, making it a versatile option for designers.

The DS28E01-100+ is available in a compact, 6-pin TSOC package, which is suitable for applications where space is at a premium. Its wide operating temperature range of -40°C to +85°C ensures reliability and performance even in harsh environments.

Whether used for protecting intellectual property, securing medical devices, or ensuring the authenticity of consumer products, the Maxim Integrated DS28E01-100+ provides a high level of security that helps manufacturers protect their brand and customers.
