Monza X UHF RFID Chips

Impinj Monza X-2K Dura and Monza X-8K Dura UHF RFID chips enable users to communicate wirelessly with the processor inside electronic devices using standard UHF Gen 2 RFID readers, unlocking many new benefits for consumer electronics manufacturers, retailers and end users. Embedded directly into the circuit board of an electronic device, Monza X chips link to the deviceโ€™s processor through a standard I2C bus, enabling the processor or a UHF reader to read and write the Monza X chip memory even when the electronic device is powered off. By enabling electronic devices to communicate with RFID readers, Monza X chips deliver a wide range of extended capabilities such as theft deterrence in the supply chain and wireless device configuration at point of sale and beyond.


Monza X chip features include:

  • 2 kbits or 8 kbits user memory accessible through both RF to reader devices and I2C interface to microprocessors
  • Impinj’s QT® technology and one time programmable memory blocks for privacy and security of sensitive information stored in the chip
  • Superior passive read/write sensitivity and the ability to boost sensitivity by supplying DC power
  • Two fully independent antenna ports, enabling multiple configurations for far field and near field RFID applications
  • Ability to wake up the microprocessor from low power states in response to RF write event, enabling power efficient electronic devices

 The Monza X Development Kit is designed for rapid prototyping of your project using Monza X chips.
