Product Details
DS28E50Q+T - 1-Wire SHA-3 Authenticator with ChipDNA
DS28E50Q+T from Analog Devices / Maxim Integrated is a DeepCover SHA-3 secure authenticator with ChipDNA PUF protection in a 6-pin TDFN exposed-pad tape-and-reel package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28E50 combines SHA3-256 challenge-response authentication, a ChipDNA physically unclonable function, true random number generation, secured EEPROM, a decrement-only counter and a unique ROM ID.
Key Advantages
Derives protected key material from a physically unclonable function and adds active die-shield countermeasures.
Combines SHA3-256 HMAC, a compliant entropy source, secured EEPROM, GPIO and a usage counter.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.

Replacement Considerations
DS28E50Q+U is a related product in the library. Confirm electrical behavior, package, pinout, ordering media and configuration before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
The linked +U order code uses the same TDFN package but a different shipping medium. Confirm quantity, packing and programming flow.
Applications
Authenticates limited-use medical, printer and industrial consumables.
Protects device identity, licensed features and authenticated GPIO control.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
FAQ
What is the main function?
SHA-3 secure authenticator
What package is used?
