Product Details
DS28E16Q+T - 1-Wire SHA-3 Secure Authenticator, 6-Pin TDFN-EP
DS28E16Q+T from Analog Devices Inc./Maxim Integrated is a 1-Wire SHA-3 secure authenticator in a 6-pin 3 x 3 mm TDFN package with exposed pad, supplied on tape and reel.
Specifications were checked against the manufacturer data sheet; distributor stock and prices require live confirmation.
Overview
DS28E16 provides SHA-3 challenge-response authentication, secured EEPROM, a unique factory-programmed 64-bit ROM identifier and a decrement-only counter. The Q+T order code selects the 6-pin TDFN-EP package on a 2,500-piece tape and reel. It is parasitically powered through the 1-Wire IO connection.
Key Advantages
SHA-3 challenge-response and protected secret storage support accessory authentication.
A single-contact 1-Wire interface reduces connector count.
Supplied in the documented tape-and-reel surface-mount package.
Electrical and environmental limits are defined by the official data sheet.

Replacement Considerations
DS28E16Q+U is a verified catalog entry. ADI lists DS28E16Q+U in the same TDFN-EP package. Confirm the +U carrier, quantity, provisioning and current availability before substitution.
Similarity of family name or package does not establish drop-in compatibility.
Manufacturer Information
ADI/Maxim DS28E16 Rev. 2 specifies the exact Q+T TDFN-EP order code, pin table and exposed-pad grounding. The manufacturer currently lists this family as recommended for new designs.
Applications
Checks peripheral identity using SHA-3 challenge-response.
Supports protected identification and cycle tracking.
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?
1-Wire SHA-3 secure authenticator
What package is used?
