Analog Devices / Maxim Integrated DS28E16 1-Wire Secure Authenticator

Analog Devices DS28E16 1-Wire Secure Authenticator integrates DeepCover^® capability to protect all device-stored data from invasive discovery. The highly integrated DS28E16 combines FIPS202-compliant Secure Hash Algorithm (SHA-3) challenge and response authentication with secured EEPROM. The DS28E16 Secure Authenticator provides a core set of cryptographic tools derived from integrated blocks, including an SHA-3 engine, 256 bits of secured user EEPROM, a decrement-only counter, and a unique 64-bit ROM identification number (ROM ID). The unique ROM ID is a fundamental input parameter for cryptographic operations and is an electronic serial number within the application. The device communicates over the single-contact 1-Wire^® bus with a parasitic supply through an internal capacitor. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.

The Analog Devices DS28E16 1-Wire Secure Authenticator is offered in compact Pb-free, RoHS-compliant WLP-6, and TDFN-EP-6 packages, ideal for space-constrained applications.
