DS28E83Q+U

DS28E83Q+U is a radiation-resistant secure authenticator that provides a core set of cryptographic tools derived from integrated asymmetric (ECC P-256) and symmetric (SHA-256) security functions. In addition to the security services provided by the hardware-implemented crypto engines, the device integrates a FIPS-compatible true random number generator (TRNG), 10Kb of secured OTP, one configurable GPIO, and a unique 64-bit ROM identification number (ROM ID). DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced security to provide the most secure key storage possible. Applications include medical consumables secure authentication, medical tools/accessories identification and calibration, accessory and peripheral secure authentication, secure storage of cryptographic keys for host controllers, secure boot or download of firmware and/or system parameters.

• ECC P-256 compute engine, FIPS 186 ECDSA P-256 signature and verification
• ECDH key exchange for session key establishment, ECDSA authenticated R/W of configurable memory
• SHA-256 OTP (one-time pad) encrypted R/W of configurable memory through ECDH established key
• TRNG with NIST SP 800-90B compliant entropy source with function to read out
• Advanced 1-wire protocol minimizes interface to just single contact
• Unique and unalterable factory-programmed 64-bit identification number (ROM ID)
• 1-wire pull-up voltage range from 2.97 to 3.63V
• Output low voltage is 0.4V max at IOL=4mA
• 6 TDFN-EP package
• Temperature range from 0°C to +50°C
