DS28E50Q+T

Specialized ICS Overview

The DS28E50Q+T is a DeepCover Secure SHA-3 Authenticator integrating Analog Devices' ChipDNA physically unclonable function (PUF) technology. It provides FIPS 202-compliant SHA-3 challenge-response authentication and HMAC capabilities. The device includes a 2Kb secured EEPROM array, a 17-bit decrement-only counter, and a unique 64-bit ROM ID. It operates on the single-contact 1-Wire bus at standard (11.7kbps) and overdrive (62.5kbps) speeds with a supply voltage range of 2.97V to 3.63V. The component utilizes an external capacitor for parasitic power and features a 6-pin TDFN-EP package.

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as supply levels may vary. Ensure the procurement channel provides original manufacturer packaging to maintain component integrity and traceability.

Specialized ICS Selection Notes

Select this component when high-assurance security is required for peripheral identification or consumable tracking. The DS28E50 is suitable for applications needing resistance to invasive attacks and cloning. Consider the 1-Wire interface compatibility with existing host controllers and verify that the 2Kb memory capacity meets data storage requirements for keys and user information.

Specialized ICS Part Context

The DS28E50 belongs to the DeepCover Secure Authenticator family from Analog Devices/Maxim Integrated. It succeeds previous generations by incorporating SHA-3 cryptography and ChipDNA PUF protection. This series targets industries requiring robust hardware-based security solutions for asset tracking and anti-counterfeiting in constrained environments.

Specialized ICS Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other DeepCover models such as the DS28E39 or DS28EL15 if SHA-3 support is not strictly required, ensuring functional compatibility with the existing 1-Wire network architecture.
