06-06-2022 | Analog Devices | Subs & Systems

Analog Devices, Inc has released the DS28E30 1-Wire ECDSA Secure Authenticator, a cost-effective solution to detect and help guard products from counterfeiting or misuse. Incorporating a fixed-function cryptographic toolbox based on the industry-standard FIPS 186 ECDSA, secure storage of keys and application data, and the single-contact 1-Wire interface, the device simply integrates into existing or new designs with minimal complexity.

The device delivers secure features to allow the use management of limited life tools, sensors, and other peripherals. These comprise a monotonic, non-resettable, decrement-only counter and 1Kbit of general-purpose EEPROM that may optionally be ECDSA protected to store application data, with end-product life-cycle information.

Each part is factory programmed with ADI public key certificate for guaranteed authenticity. It offers a wide operating range of 1.62V-5.25V, -40C to +85C. It is provided in a small 1.2mm x 1.4mm 4-ball WLP with 0.5mm pitch.
