Product Details
DS28E83Q+T - Radiation-Resistant 1-Wire Secure Authenticator
DS28E83Q+T from Analog Devices / Maxim Integrated is a DeepCover ECC-P256 and SHA-256 secure authenticator with radiation-resistant 10-Kbit OTP in a 6-pin TDFN exposed-pad tape-and-reel package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28E83 combines ECDSA-P256, ECDH, SHA-256/HMAC, a compliant random source, radiation-resistant OTP, authenticated GPIO and a unique 64-bit ROM ID for medical and peripheral authentication.
Key Advantages
Retains programmable manufacturing, calibration and credential data through radiation sterilization up to 75 kGy.
Provides public-key and symmetric authentication, encrypted memory access and authenticated GPIO over one contact.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.

Replacement Considerations
DS28E83Q+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 device with different shipping media. Confirm handling, programming and sterilization traceability.
Applications
Authenticates sterilized disposable sensors, tools and accessories.
Keeps one-time-programmed calibration and certificate data through radiation processing.
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
