MAX66250ESA+

MAX66250 secure authenticator combines FIPS 202-compliant secure hash algorithm (SHA-3) challenge and response authentication with secured EEPROM. The device provides a core set of cryptographic tools derived from integrated blocks including a 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 used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application. The device communicates over an RF interface compliant with ISO/IEC 15693. Typical applications are medical tools/accessories authentication and calibration, printer cartridge configuration and monitoring, system intellectual property protection, NFC-enabled embedded systems, asset tracking, access control, driver identification, E-cash.
