DS28C39Q+U

DS28C39Q+U is a DeepCover secure ECDSA bidirectional authenticator with ChipDNA PUF protection. It incorporates Maxim’s patented ChipDNA™ and features a physically unclonable function (PUF) to provide a cost-effective solution with the ultimate protection against security attacks. Using the random variation of semiconductor device characteristics that naturally occur during wafer fabrication, the ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage. Attempts to probe or observe ChipDNA operation modify the underlying circuit characteristics, preventing the discovery of the unique value used by the chip's cryptographic functions. It is used in applications such as authentication of medical sensors and tools, secure management of limited-use consumables, IoT node authentication, peripheral authentication, reference design license management, printer cartridge identification, and authentication.
