• Direct NFC to SPI interface
  • 5mA energy harvest
  • 106 to 848kbit/s data transfer rate
  • Built-in 1kbit high endurance EEPROM (>1Mu write cycles)


  • Most cost efficient and easiest way to implement NFC
  • Power positive, longer battery lifetime, allows batteryless designs
  • Fast data transfer for firmware upgrades or data intense applications
  • Longest lifetime of EEPROM even in challenging environments
