Features and Benefits

  • HF Interface at 13.56MHz
  • User EEPROM Authenticated Memory Page Read/Write Transactions
  • User EEPROM Page/Block Read/Write Transactions
  • Secure Transaction that Writes “Secret Keys” and Computes Message Authentication Code

Product Details

The MAX66240 evaluation kit (EV kit) reference board is a ready-to-use PCB that showcases one of Maxim’s MAX662xx family of secure HF ICs. The board is built with a hexagonal-shaped antenna construction (see the EV Kit Photo and Figure 3 in the full data sheet) tuned to 13.56MHz.

The EV kit is a platform that allows designers, test, and systems engineers to evaluate our MAX66240 tag solution. The EV kit allows users to evaluate the performance and capabilities of certain key features of the part and is a great platform to get started on a new NFC/RFID tag design.

Applications

  • Access Control
  • Asset Tracking
  • Medical Sensor Authentication and Calibration
  • Printer Cartridge Configuration and Monitoring
  • System Intellectual Property Protection

Product Details

The MAX66300-24x evaluation system (EV system) comprises a MAX66300 evaluation kit (EV kit) and a MAX66242 tag. The MAX66300 EV kit combines a RFID reader for contactless communication at 13.56MHz and a SHA-256 secure authenticator coprocessor. The RFID reader covers the ISO 15693 standard and the authenticator coprocessor is based on the FIPS 180-4 standard. The MAX66242 tag operates as a solution covering the ISO 15693 standard. By pairing the MAX66300 EV kit with the MAX66242 EV kit into an EV system, EV kit software can operate to show a secure challenge and response authentication and other part specific functionality.

Applications

  • Asset-Tracking Readers
  • Authentication of Consumables
  • Blood Glucose Meters/Monitors
  • Handheld Reader Modules
  • Readers in Printers (Ink Cartridge)
  • Secure Access Control
