Product Details
DS28C50Q+T - DS28C50 ChipDNA SHA-3 Secure Authenticator
DS28C50Q+T from Analog Devices Inc./Maxim Integrated is an I2C secure authenticator combining SHA-3 HMAC, ChipDNA PUF key protection, a TRNG and 2 Kb secure EEPROM.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28C50 uses a physically unclonable function to derive protected key material and performs SHA-3 challenge-response authentication without exposing the secret.
Key Advantages
ChipDNA PUF and an actively monitored die shield resist key extraction and invasive attacks.
A hardware SHA-3 engine, TRNG, protected EEPROM, authenticated GPIO and decrement counter simplify secure consumable designs.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
