Product Details

The MAX66301-25x evaluation system (EV system) comprises a MAX66301 evaluation kit (EV kit) and a MAX66250 tag. The MAX66301 EV kit combines an RFID reader for contactless communication at 13.56MHz 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.

The MAX66301NFC# is an enclosed version of the MAX66301 EV kit that is suitable for use in a manufacturing environment. The included antenna can be connected by the 50Ω coaxial cable provided with the MAX66301NFC# kit, or a custom antenna and cable may be connected for optimal performance in the targeted environment.

Analog Devices provides a simple graphical user interface (GUI) to invoke commands and create scripts that generate combinations of these commands for reading and writing the memory of the MAX66250 and setting memory protections. The operator selects input data and operations to perform, and the software handles the details.
