A passive RFID dual-protocol electronic tag chip

Abstract

The invention provides a passive RFID dual-protocol electronic tag chip. The passive RFID dual-protocol electronic tag chip comprises a protocol A processing module, a protocol B processing module anda memory; the Protocol A processing module and the protocol B processing module are respectively connected with the memory; the protocol A processing module is used for receiving and decoding a working command sent by read-write equipment supporting a protocol A, writing data into the memory or reading the data of the memory, encoding according to a data encoding format required by the protocol A, and returning the encoded data to the read-write equipment supporting the protocol A; And the protocol B processing module is used for receiving and decoding a working command sent by the read-writeequipment supporting the protocol B, writing data into the memory or reading the data of the memory, encoding according to a data encoding format required by the protocol B, and returning the encodeddata to the read-write equipment supporting the protocol B. The passive RFID dual-protocol electronic tag chip has the beneficial effects that the dual protocols share one memory, so that the cost ofthe single RFID tag supporting the dual protocols is obviously reduced, and the area is reduced.

Description

technical field [0001] The invention relates to an electronic label, in particular to a passive RFID dual-protocol electronic label chip. Background technique [0002] In the field of radio frequency identification (RFID), there are multiple communication protocols, and different communication protocols have different characteristics due to different frequency bands and application scenarios. For example, the RFID electronic tag chip conforming to the ISO 14223 communication protocol works in the low-frequency band and has good penetration into water, human or animal bodies and other conductive media, but the speed, distance, and anti-collision performance are poor; The RFID electronic tag chip of the -6C communication protocol works in the ultra-high frequency band, and has the characteristics of high speed, long distance, and strong multi-tag reading performance, but the penetration of conductive media is weak. [0003] With the rapid development of applications based on ...

AI Technical Summary

Problems solved by technology

[0005] 1) There are two tag chips in the tag, the tag cost is higher and the area is larger

[0006] 2) The data of the two tag chips in the tag is managed separately, the data management cost is very high, and the data of the two tag chips is prone to inconsistency
