The invention discloses a program upgrading application circuit and a program upgrading application device comprising the program upgrading application circuit. The program upgrading application circuit comprises a first interface unit, a controller module and a voltage-stabilized power supply control module; the first interface unit is electrically connected to the controller module and to the voltage-stabilized power supply control module and is used for receiving an external data signal and a first input voltage; the controller module is electrically connected with the voltage-stabilized power supply control module, and the voltage-stabilized power supply control module comprises a first power supply unit and a second power supply unit; when the controller module receives the data signal, the controller module outputs a power supply enable signal to the voltage-stabilized power supply control module to control the first power supply unit to be electrically cut off and stops providing a driving voltage, and the second power supply unit outputs a driving voltage to the controller module according to the received first input voltage; when the controller module does not receive the external data signal, the first power supply unit outputs the driving voltage to the controller module according to the received external power supply voltage.
Description
technical field [0001] The present application relates to the field of electronic technology, in particular to a program upgrade application circuit and a program upgrade application device. Background technique [0002] With the continuous development of science and technology and the progress of the times, various electronic products have been widely used in all walks of life in society, and various functions in electronic products are also constantly updated and upgraded to meet the needs of use. Among various electronic products, most of them use a programmable control unit (Microcontroller Unit, MCU) to control the product to realize corresponding functions. [0003] At present, when the control units in various electronic products on the market are not assembled, the programs in the control units are upgraded or burned, and then assembled into electronic products. When the functions in the electronic product need to be updated or the program is abnormal, and the progr...
