July 31, 2019 – Mouser Electronics, a distributor of electronic components focused on introducing new products and providing massive inventory, is now stocking Maxim Integrated's DS28E39 and DS28E84 DeepCover® Authenticators. With these secure authenticators, engineers can add additional layers of protection for applications such as Internet of Things (IoT) nodes, device management, security peripherals, and medical sensors.
The DS28E39 is a secure authenticator based on the Elliptic Curve Digital Signature Algorithm (ECDSA) public key that uses Maxim's patented ChipDNATM Physical Non-Cloneable Technology (PUF) to help protect against security attacks. Any attempt to detect or observe ChipDNA operations will alter the underlying circuit characteristics, thereby preventing the unique value used by the chip encryption function from being discovered.
The DS28E84 is a radiation safety certifier designed for medical devices. Electronic medical devices use standard non-volatile memory (NVM) for automatic identification and storage of calibration and manufacturing data, but high-radiation exposure during sterilization can damage and damage such memories. With a radiation protection capability of up to 50 kGy, the DS28E84 IC allows users to set manufacturing or calibration data prior to medical sterilization, preventing unauthorized reuse and improving patient safety.
Both the DS28E39 and DS28E84 communicate over standard speed and overclock speeds over a single-contact 1-Wire® bus for easy integration into the design. The communication uses the 1-Wire protocol, which uses the ROM ID as the node address in a multi-device 1-Wire network.
