Product Details
DS28E36Q+T - 1-Wire ECC and SHA-256 Secure Authenticator
DS28E36Q+T from Analog Devices / Maxim Integrated is a DeepCover secure authenticator with ECC-P256, SHA-256 and 8-Kbit EEPROM in a 6-pin TDFN exposed-pad tape-and-reel package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28E36 combines ECDSA-P256 signing and verification, ECDH key exchange, SHA-256/HMAC, a compliant true random source, protected EEPROM, authenticated GPIO and a unique ROM ID.
Key Advantages
Supports asymmetric authentication and key exchange without distributing a shared device secret.
Integrates 8-Kbit protected EEPROM, two authenticated GPIO pins and a nonvolatile 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
DS28E36Q+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 device and TDFN package with a different shipping medium. Confirm handling and production 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
