Maxim DS28E16Q 1-Wire Secure SHA-3 Authenticator

Shenzhen Mingjiada Electronics Co., Ltd., a globally renowned electronic component supply chain service provider, supplies Maxim's DS28E16Q 1-Wire Secure SHA-3 Authenticator. This device integrates powerful SHA-3 encryption algorithms with an ultra-simple 1-Wire interface, delivering a cost-effective security solution for diverse electronic systems.

Embedding DeepCover® security technology, this authenticator can be integrated into diverse electronic devices to secure systems, accessories, and data. It effectively prevents security threats such as cloning, tampering, and man-in-the-middle attacks.

【DS28E16Q Core Features and Security Mechanisms】

The DS28E16Q is a protection solution based on DeepCover security technology. Its core is the FIPS 202-compliant SHA-3 secure hash algorithm, enabling challenge-response authentication.

Compared to traditional authentication schemes, the SHA-3 algorithm offers superior resistance to attacks, ensuring security even against future computational threats.

The DS28E16Q authenticator integrates multiple critical cryptographic tools, including an SHA-3 engine, 256-bit secure user EEPROM, a 17-bit decrement-only counter, and a unique 64-bit ROM identification code.

The unique ROM ID serves not only as a fundamental input parameter for cryptographic operations but also functions as an electronic serial number within applications, seamlessly combining identity authentication with device identification.

【DS28E16Q Simplified Interface and Electrical Characteristics】

The DS28E16Q communicates via a single-wire 1-Wire bus. The 1-Wire protocol's greatest advantage lies in its extreme interface simplification, requiring only a single signal line for both data transmission and power delivery.

This minimalist design utilizes parasitic power from internal capacitors, significantly reducing the need for external power sources.

Within a multi-device 1-Wire network, each DS28E16Q's unique ROM ID serves as its node address, enabling the host to precisely address individual authenticators within the network.

The DS28E16Q operates over a wide voltage range from 1.71V to 3.63V, covering a broad spectrum of low-power applications. Its operating temperature range of -40°C to +85°C makes it suitable for industrial and automotive applications.

【DS28E16Q Packaging and Physical Specifications】

To accommodate space-constrained applications, the DS28E16Q offers two compact packaging options: TDFN-EP-6 and WLP-6.

Both packages are lead-free and RoHS compliant, meeting environmental requirements.

The TDFN-EP-6 package offers excellent thermal performance, while the WLP (Wafer Level Package) provides an extremely small footprint, making it suitable for highly integrated applications.

The DS28E16Q also provides ±8kV HBM ESD protection, effectively preventing damage from electrostatic discharge and enhancing reliability in harsh environments.

【DS28E16Q Application Scenarios】

The DS28E16Q finds extensive application across numerous fields requiring security authentication.

In medical devices, it enables the identification and calibration of medical tools and accessories, ensuring only factory-certified peripherals can operate with host equipment.

This is critical for maintaining measurement accuracy and patient safety.

In consumer electronics and industrial settings, the DS28E16Q authenticator secures accessories and peripherals, preventing unauthorized compatible products from compromising system performance and reliability.

Battery authentication and charge cycle tracking represent another critical application, ensuring only safe, original manufacturer batteries are used with devices while monitoring battery usage.

The DS28E16Q also enables secure storage of encryption keys for host controllers, providing a secure key management solution to prevent critical information leakage.
