Maxim Integrated DS28E01G-100+T&R

The DS28E01G-100+T&R from Maxim Integrated is a highly secure, single-chip, 1Kb EEPROM with SHA-1 authentication. Designed to add an extra layer of security to your hardware, this chip is ideal for preventing counterfeiting, unauthorized usage, and ensures secure data storage. It is especially well-suited for applications in medical devices, industrial equipment, and consumer products where protection of sensitive data and intellectual property is paramount.

This robust security device combines a large user-programmable EEPROM with a powerful SHA-1 cryptographic engine, enabling it to perform high-security mutual authentication. The DS28E01G-100+T&R ensures that only authorized accessories and components are used in a system. It uses a challenge-and-response scheme to verify the authenticity of a device, which is crucial in preventing cloning and ensuring the integrity of the communication.

The device operates over a wide voltage range of 2.8V to 5.25V and is specified over the -40°C to +85°C temperature range, making it suitable for a broad spectrum of applications. The DS28E01G-100+T&R comes in a compact 6-pin TSOC package and is provided in tape and reel form, denoted by the T&R suffix, which is ideal for automated manufacturing processes.

Key features of the DS28E01G-100+T&R include:

• 1024 bits of EEPROM memory partitioned into four pages of 256 bits, providing ample storage for application-specific data, including encryption keys and digital certificates.
• Integrated SHA-1 engine that can compute 160-bit cryptographic hashes, a standard algorithm used for secure data verification.
• Bidirectional challenge-and-response authentication protocol that helps prevent unauthorized device cloning and ensures data integrity.
• Simple single-contact, 1-Wire® interface that facilitates seamless integration into designs with minimal pin requirements, reducing complexity and cost.
• High-reliability data retention with EEPROM endurance of at least 100,000 write cycles and data retention of over 10 years, ensuring the longevity and durability of the stored information.

The DS28E01G-100+T&R's advanced security features, ease of integration, and dependable data retention make it an excellent choice for securing your next project or product against the evolving threats of tampering and piracy.
