Maxim Integrated DS28E15Q+U DeepCover Secure Authenticator
The DS28E15Q+U from Maxim Integrated is a highly secure, single-chip solution designed to provide robust authentication with minimal complexity. This DeepCover secure authenticator incorporates advanced cryptographic algorithms to ensure the authenticity of devices, peripherals, or accessories in a system. It is an ideal choice for safeguarding communication between components in applications where security and integrity are paramount.
At the heart of the DS28E15Q+U is a FIPS/NIST-compliant SHA-256 hash engine. This cryptographic engine, combined with a unique 64-bit ROM identification number (ROM ID), provides a high level of security through a challenge-and-response authentication process. The device's 512 bits of user-programmable EEPROM allow for the secure storage of application data, keys, or certificates.
The DS28E15Q+U operates over the standard 1-Wire interface, which requires only a single data lead and a ground return for communication. This simplifies the hardware design and reduces the overall system's footprint, making it an efficient solution for space-constrained applications. Its wide operating voltage range of 3.3V to 5.5V and extended temperature range make it versatile for various environments and use cases, from industrial to consumer electronics.
Maxim Integrated has equipped the DS28E15Q+U with several protective features to ensure the highest level of security. The chip includes mechanisms like secure storage for the secret key, the ability to lock memory and configurations irreversibly, and protection against physical attacks, such as glitch and timing attacks. These features make it extremely difficult for unauthorized parties to compromise the device or the system it secures.
With its compact form factor, the DS28E15Q+U is available in a 6-pin TSOC package, which is suitable for PCB mounting and is RoHS compliant. This secure authenticator is an excellent choice for manufacturers looking to protect their products from counterfeiting, ensure supply chain integrity, or enforce software licensing and warranty provisions.
Whether you're securing medical devices, IoT nodes, consumables identification, or peripheral authentication, the Maxim Integrated DS28E15Q+U provides a high-security solution that is both easy to implement and cost-effective.
