Analog Devices / Maxim Integrated MAX66250 EEPROM Secure Authenticators
Analog Devices MAX66250 EEPROM Secure Authenticators combines FIPS 202-compliant Secure Hash Algorithm (SHA-3) with secured EEPROM. The device provides a core set of cryptographic tools derived from integrated blocks. The tools include 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 Analog Devices device communicates over an RF interface compliant with ISO/IEC 15693.Features
