DS28E39 - Maxim Integrated

DS28E39 DeepCover Secure ECDSA Bidirectional Authenticator

The DS28E39 is an ECDSA public-key-based bidirectional secure authenticator that incorporates Maxim’s patented ChipDNA™ feature, 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.
