DS28E36Q+U

DS28E36Q+U is a DeepCover® secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC-P256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware-implemented crypto engines, the device integrates a FIPS/NIST true random number generator (RNG), 8Kb of secured EEPROM, a decrement-only counter, two pins of configurable GPIO, and a unique 64-bit ROM identification number (ROM ID). This unique ROM ID is used as a fundamental input parameter for cryptographic operations and also serves as an electronic serial number within the application. The DS28E36 communicates over the single-contact 1-Wire® bus at overdrive speed. Applications include IoT node crypto-protection, accessory and peripheral secure authentication, secure storage of cryptographic keys for a host controller, secure boot or download of firmware and/or system parameters.
