Abstract：Radio Frequency Identification(RFID)is a technology to identify the target object by transmitting and receiving ra-dio frequency signals,and thus obtain the relevant parameters of the target object.As UHF RFID technology is applied in more and more fields,in order to adapt to various application requirements more quickly,this paper realizes UHF RFID tag digital baseband in the form of SOC.In the whole digital baseband design,the physical link layer of the tag is realized by hardware,including FM0/Miller coding module,PIE decoding module,CRC coding/decoding module,etc.At the same time,the tag recognition layer is de-signed by using the open source RISC-V kernel Hummingbird E203 and some additional hardware.By running on FPGA,the cor-rectness is design and its conformity to the ISO/IEC_18000-6C communication protocol are verified.
