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.

• Two GPIO pins with optional authentication control
• RNG with NIST SP 800-90B compliant entropy source with function to read out
• 17-bit one-time settable, nonvolatile decrement-only counter with authenticated read
• 8Kbits of EEPROM for user data, keys, and certificates
• Unique and unalterable factory-programmed 64-bit identification number (ROM ID)
• 1-wire pullup voltage is 3.3V typical
• Leakage current is +1µA maximum
• Data retention is 10years at TA=+85°C
• 6 TDFN-EP package
• Temperature range from -40°C to +85°C
