description: The theme of the final qualification work: âTemporary accuracy of STM32 microcontrollers in low power consumption modesâ.
This work is devoted to the study of the characteristics of the microcontrollers of the series. STM32 to learn how to reduce power consumption. Tasks that were solved during the study:
1. To study the operation of the timing circuit MK series STM32.
2. To study the work of the family of processor cores Cortex.
3. To study the operation of microcontrollers on the example of MK STM32L0 and STM32F4.
4. To determine the parameters of microcontrollers of the STM32 series that best meet the requirements of low consumption.
The work was carried out on the basis of the study of theoretical material, in order to identify the parameters that affect energy consumption. A review of the operation of the controllers was conducted on the example of MK STM32L0 and STM32F4. The analysis was carried out by comparing the functionality and operation of the above models. Based on what, it was concluded about which operating modes are fundamental for reducing consumption. And also, what devices of the periphery of MK are able to influence this decrease.
