Introduction

The 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 de- rived 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.

The MAX66250 integrates Analog Devices' DeepCover capability to protect all device-stored data from invasive discovery. In addition to the SHA-3 engine for signatures and authenticated writes, the MAX66250 includes a 256-bit EEPROM for user memory, SHA-3 secret storage, 17-bit decrement counter, and control registers. The device communicates through an ISO/IEC 15693 interface.
