The invention provides a chip pin function reconstruction method and a chip, and relates to the technical field of electronic circuits. Through a software configuration mode, the processing unit transmits the enable signal to each input/output circuit and transmits the reconfiguration control signal to each switching circuit according to the acquired configuration information, so that the reconfiguration of the input/output circuits is realized by controlling the closing or opening of the different switching circuits. Pins conducted by the input and output interfaces connected with the input and output circuits are flexibly adjusted by adjusting the input and output circuits, so that functions of different pins on the chip are multiplexed and migrated, function extension of the chip is more flexible, the functions of the input and output interfaces on the chip can be used to the maximum extent without being limited by packaging, and the chip is more flexible in function extension. In addition, packaging can b
