UHF RFID NFC INTEGRATED CIRCUIT AND ELECTRONIC TAG FOR PROCESSING UHF RFID SIGNAL AND NFC SIGNNAL

摘要

An integrated circuit is disclosed. The integrated circuit rectifies the UHF RFID signal obtained through the first antenna using a first rectifier and the UHF RFID tag physical layer generating a first DC voltage, and a second rectifier using the NFC signal obtained through the second antenna An NFC tag physical layer that rectifies and generates a second DC voltage, a microcontroller unit, and data to be processed and data to be processed by the UHF RFID tag physical layer, under the control of the microcontroller unit, and the A nonvolatile memory device that stores data processed by the NFC tag physical layer and data to be processed, and detects that any one of the first DC voltage and the second DC voltage is input, and detects the detected DC voltage. It includes one of the UHF RFID tag physical layer and the NFC tag physical layer, the microcontroller unit, and a detector that supplies the nonvolatile memory device.
