Rocky100 – RFID tag ICs for IoT solution development

Rocky100 RFID tag ICs packaged in QFN 4x4mm

RFID tag ICs for external sensors and actuators

The Rocky100 is a UHF RFID IC with advanced capabilities for developing battery-free sensor tags.

The device features a configurable SPI port (master/slave) for communication with external devices and a configurable power output for driving those external devices from the energy harvested from the UHF RF field.

The tag is compatible with EPC C1G2 RFID commercial readers. No custom hardware or custom commands are required.

The Rocky100 is ideal for developing battery-free devices such as sensors, actuators or displays. These devices will help in asset or process monitoring applications as they provide a unique identification number plus data from the associated sensor without the need for batteries.
