The present invention provides an RFID tag chip suitable for block chain applications, including: an MCU module, used to control the work of the entire chip and the operation calculation of the algorithm; an RF module, connected to the MCU module signal, for sending or receiving data; a storage module for storing algorithms and data; and a power management module; the RFID tag chip further includes a Hash operation module, which is signally connected to the MCU module for receiving the data to be encrypted sent by the MCU module, and Encrypt the data to be encrypted and feed it back to the MCU module; the MCU module sends the encrypted data to the network through the RF module, thereby realizing the interaction between the RFID tag chip and the block chain; the power management module provides According to the MCU module, the working voltage is provided to the MCU module, and the MCU can be controlled to enter a low power consumption working state. The present invention also provides a control method for the above-mentioned RFID tag chip.
Description
technical field [0001] The invention relates to the field of RFID, in particular to an RFID tag chip suitable for block chain applications and a control method thereof. Background technique [0002] RFID on the market is only used as an electronic tag in logistics and clothing industries. RFID tag chip is a large-scale and complex system, which includes three parts: RF analog front-end, baseband controller and non-volatile memory. The baseband controller is to process the information received by the RF front end, read and write the memory according to the corresponding instructions, and return the processed information to the RF front end for modulation and feedback, which plays a role of control center in the whole system . Existing RFID tags can be divided into low-frequency series, high-frequency, ultra-high-frequency, microwave, etc. according to different operating frequencies. The higher the operating frequency, the higher the transmission distance and the greater th...
