General Description

The DS28E38 is an ECDSA public key-based secure authenticator that incorporates Maxim’s patented ChipDNA™ PUF technology.

ChipDNA technology involves a physically unclonable function (PUF) that enables the DS28E38 to deliver cost-effective protection against invasive physical 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.
