Description

Magnetic induction integrated circuit chip with address code and serial-parallel double-channel heat standby Technical Field The invention relates to the field of integrated circuit chips, in particular to a serial-parallel double-channel hot standby magnetic induction integrated circuit chip with address codes. Background The magnetic induction integrated circuit chip has very wide application scenes, and most application scenes need to write address codes to a plurality of magnetic induction integrated circuit chips, so that the position of each magnetic induction integrated circuit chip is known, and the follow-up work can be performed. If the magnetic induction integrated circuit chips are connected through a serial single bus, the magnetic induction integrated circuit chips determine the chip positions according to the arrangement sequence of the magnetic induction integrated circuit chips, for example, the magnetic induction integrated circuit chip with data lines, keys and a magnetic induction keyboard of the Chinese patent with the publication number of CN117270701B are authorized. If the magnetic induction integrated circuit chips are connected through a parallel single bus, the magnetic induction integrated circuit chips determine the chip positions by means of the address codes thereof, for example, the Chinese patent with the publication number of CN120049875B is entitled "a magnetic induction integrated circuit chip with address codes, keys and a magnetic induction keyboard". The magnetic induction integrated circuit chip connected through the parallel single bus needs a special jig in the code writing process, and mainly comprises the following two modes: First, write address code command is written on the chip by loading magnetic element, then the magnetic element is loaded on the next chip to write address code command, and writing of address codes of all chips is completed repeatedly in turn. The keyboard is provided with hundreds of chips, the hundreds of chips are needed to be repeated for times, the go is needed to be repeated for 400 times, the task of writing address codes is needed to be completed for four times, a special machine is needed to load magnetic elements on the chips, no matter in a mode of moving the magnetic elements by a manipulator or in a mode of loading electromagnetic coils to correspond to each chip, or corresponding magnetic elements are arranged above each magnetic induction chip, the magnetic elements correspond to the magnetic induction chips when writing codes by pressing down, or other modes are needed to be used for writing in a large scale, and an external jig is needed. After the corresponding product is maintained and sold in the mode, a defective product exists in hundreds of magnetic induction integrated circuit chips, the serial number of the defective product is required to be known, a special instrument is used for replacing the chip with the serial number address, and if a blank chip is stuck to the chip for burning, the method is more troublesome. For example, the Chinese patent with the bulletin number of CN120049875B is entitled "a magnetic induction integrated circuit chip with address code, a key and a magnetic induction keyboard", all keys of the Chinese patent are connected in parallel, each integrated circuit has unique address code corresponding key information, the key information is connected in parallel and independent, one integrated circuit breaks the key which does not affect other keys, the reliability is better (described in the [ 0033 ] section of the specification), and therefore the technical problems in the prior art are solved, namely the integrated circuits corresponding to n keys of the existing magnetic induction keyboard are connected in series and cascaded (for example, the Chinese patent with the bulletin number of CN117270701B is entitled "a magnetic induction integrated circuit chip with a data line, a key and a magnetic induction keyboard"), if one key is broken, the key information is not available, the light information is not available, and the whole keyboard is directly paralyzed and cannot be normally used, and the maintenance or replacement cost is high (described in the [ 0002 ] section of the specification). The address code writing process is recorded in detail in the [ 0058 ] section of the specification, wherein the first magnetic element 61 moves from top to bottom according to the self-defined sequence position above each magnetic induction integrated circuit chip with the address code, when the first magnetic element 61 moves above the magnetic induction integrated circuit chip with the sequence position 1, the magnetic induction integrated circuit chip with the sequence position 1 senses voltage change through magnetic induction, meanwhile, the magnetic induction integrated circuit chip with the sequence position 1 receives an address code instruction and the address code 1, then a number 1 is used as th
