With the development of black technology, the power consumption requirements of portable electronics are getting higher and higher, compared to the microcontroller performance requirements it is increasingly low power consumption, many microcontroller manufacturers are saying their products of low-power microcontroller, or ultra-low-power microcontroller, but many can not reach the low-power requirements of product development, the following Shenzhen Yufan microcontroller development engineers will explain how to choose the right low-power microcontroller The following microcontroller development engineer will explain how to choose the right low-power microcontroller.

        1, low voltage and clock frequency

        When the microcontroller is running in active mode, this is a good way to reduce the power consumption of the microcontroller. If the program keeps the microcontroller in a running state, so the selected microcontroller runs at the lowest clock speed and then runs them at the lowest voltage according to the selected clock frequency. The microcontroller is programmed to control the operating mode of the microcontroller for the lowest power consumption.

        2. Sufficiently small memory

        In short, the larger the selected microcontroller memory, the more power it will consume. Therefore, when choosing a microcontroller, memory is enough to use, the memory will be controlled in the minimum range, can minimize the power consumption of the microcontroller.

Low power consumption microcontroller

        3, simple code

        Microcontroller in the development, should try to simplify the code, so that the microcontroller in the operation of the time can spend less time, rapid response to the microcontroller function program, simple instruction logic can not only effectively reduce the power consumption of the microcontroller can also speed up the device response speed.

        4, the use of sleep standby program instructions

        When developing products, in order to improve the length of use of the product, in the program instructions are often used in sleep standby mode, can effectively save power, greatly enhance the use of the product time. According to the introduction of the above 4 points, we can effectively reduce the development cost when choosing a suitable development of low-power microcontroller according to the above introduction. However, it should be noted that low-power microcontrollers also need to take into account the power consumption of other peripheral components, and are not limited to the power consumption of the microcontroller.
