Maxim Integrated DS28E36BQ+T DeepCover Secure Authenticator

The DS28E36BQ+T is a highly secure, low-power device from Maxim Integrated that provides robust protection against invasive and non-invasive attacks. It is part of Maxim's DeepCover® lineup of secure authenticators designed to safeguard the integrity and authenticity of products through advanced cryptographic operations and physical security mechanisms.

This secure authenticator integrates an asymmetric ECDSA (Elliptic Curve Digital Signature Algorithm) engine, which is compliant with the FIPS 186 specified P-256 curve. This cryptographic tool enables the DS28E36BQ+T to generate high-quality, 256-bit ECC public/private key pairs, which are essential for implementing digital signatures and providing a secure boot or secure download environment for various applications.

One of the core features of the DS28E36BQ+T is its ChipDNA™ technology. This proprietary physical unclonable function (PUF) circuitry provides a unique and immutable identity for each chip, which is virtually impossible to replicate or reverse-engineer. This PUF-generated key serves as a foundational element for the device's security, ensuring that stored data remains protected even in the event of a physical attack on the silicon itself.

The device also includes a secure storage for 3KB of user EEPROM, which can be segmented into multiple user-defined zones with separate access control. This allows for secure storage of sensitive data such as cryptographic keys, certificates, and manufacturing details. The EEPROM is also endurance rated at 100,000 write cycles and has a data retention period of 10 years at +85°C, ensuring long-term reliability of stored data.

Additionally, the DS28E36BQ+T offers a decrement-only counter that can be used for tracking the usage and limiting the lifespan of consumables or for logging events. The device is designed to operate over the standard -40°C to +85°C temperature range and is available in a compact, 6-pin TDFN package, making it suitable for a wide array of applications including medical devices, IoT nodes, and secure peripherals.

With its advanced security features and robust construction, the DS28E36BQ+T from Maxim Integrated stands as a formidable solution for any application requiring stringent security measures to protect against counterfeiting, unauthorized use, and other malicious threats.
