This invention relates to a process for the realization of a multifunctional mcu as well as a multifunctional mcu and thus belongs to the region of the electronics. The method comprises: detecting the input by the user functional operating instructions. The the functional operation command corresponding function identification, then, fingerprints of the user and, in accordance with the fingerprints is scanned in the user identifies. The the functional operation command corresponding function data storage, then, the data are stored in a storage space provided for this purpose. The function corresponding to the functional operation command charging, the preset device is then charged. The above-mentioned multifunctional mcu has: an entry module, an identification module, a memory module and a recharge module. This invention, functions such as operation command, by means of detection function to be detected, which to carry out the operation command corresponding performance operation, and it is realized functions, such as identification, data storage, charging, and thus simplified it provides for the application for the user.
