MAX66250/MAX66301 NFC Secure Authenticators and Coprocessors

Analog Devices' MAX66250 and MAX66301 NFC secure authenticators and coprocessors provide a complete contactless security solution. These products feature the latest SHA-3 challenge-and-response cryptographic algorithm coupled with NFC ISO 15693 interface to authenticate and protect against security attacks and prevent counterfeits.

The MAX66301-25x evaluation system (MAX66301-25XEVKIT#) comprises a MAX66301 evaluation kit (EV kit) and a MAX66250 tag. The MAX66301 EV kit combines an RFID reader for contactless communication at 13.56 MHz and a SHA-3 secure authenticator coprocessor. The RFID reader covers the ISO 15693 standard, and the authenticator coprocessor is based on the FIPS202-compliant standard. The MAX66250 tag operates as a solution covering the ISO 15693 standard and combines FIPS202-compliant secure hash algorithm (SHA-3) challenge and response authentication with secured EEPROM. By pairing the MAX66301 with the MAX66250 into an EV system, the EV kit software can operate to show a secure challenge and response authentication and other part-specific functionality.

Features
