Description
Technical field
The utility model relates to RFID chip.
Background technology
Along with the development of Internet of Things and mobile Internet, RFID and various IC-card are applied more and more extensive, comprehensively popularizing particularly along with smart mobile phone, mobile phone radio frequency recognition function and NFC function are also day by day popularized, and the multifunctional unit application of RFID and IC-card increases fast.
Traditional RFID and IC-card RFID chip used are all unique energy and handshake interface with radio-frequency antenna, and this simple version makes the encapsulation of RFID chip convenient, and cost is lower, for the Rapid Popularization of RFID provides condition.
But along with the development of RFID application, we find, traditional RFID chip is " single function ".Namely be merely able to carry out message exchange according to the default homologous ray of the set design and devdlop system of chip.And the change of IC-card holder or RFID application scenarios all can not feed back in application system and goes, this multifunctional unit that RFID is applied brings difficulty.
The label so just making us need to carry and IC-card card can get more and more, and can not meet some basic interactive demands simultaneously.
Summary of the invention
The purpose of this utility model solves when RFID chip can not realize basic interaction function and RFID chip multifunctional unit to solve user to the problem of user's right to choose of multiple function.
The technical scheme adopted for realizing the utility model object is such, and a kind of RFID chip with interactive switch input port, this RFID chip comprises radio-frequency interface circuit unit, calculation control unit and storage unit.
It is characterized in that: also comprise input interface circuit unit.
Described input interface circuit unit comprises the first resistance, the second resistance, unidirectional gauge tap and switch control rule position.Described first resistance becomes bleeder circuit with the second resistor group, and described first resistance one end access power supply, the other end is divided into two-way, and wherein a road is connected in series after the second resistance by chip outside connected switch K
c0rear ground connection, an other road connects the control bit C of unidirectional gauge tap by calculation control unit
0the input interface of access calculation control unit after controlling.The two ends of described unidirectional gauge tap are respectively K
0＇ and K
0＂ terminal.Described outside connected switch K
c0the one end linked with the second resistance is K
0terminal.
What deserves to be explained is, described outside connected switch K
c0control as time closed by the external world, K
