Product Details
DS28C16Q+T - DS28C16 I2C SHA-3 Secure Authenticator
DS28C16Q+T from Analog Devices Inc./Maxim Integrated is a hardware SHA-3 secure authenticator with protected secret storage, secured EEPROM, a decrement-only counter and a factory-unique ROM ID.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28C16Q+T combines FIPS 202 SHA-3, FIPS 198 HMAC, protected secrets, secured EEPROM and a unique identifier over I2C up to 1 MHz.
Key Advantages
Hardware challenge-response authentication keeps secret material out of normal host firmware.
A nonvolatile decrement-only counter supports authenticated usage and lifecycle tracking.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
