DS28E39 Overview
Description
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 fabrication, the ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage.
Key Features
- a physically unclonable function (PUF) to provide a cost-effective solution with the ultimate protection against security attacks
- The DS28E39 communicates over the single-contact 1-Wire® bus at both standard and overdrive speeds
- The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network
