资料介绍

1 Introduction Applications strive for high performance within constrained energy budgets. Increasing system level requirements does not allow for compromises on performance, but pushes for low energy budgets to extend product use times. The Kinetis microcontroller family includes internal power management features that can be used to control the microcontroller's power usage and assist reaching the targets of embedded designs. This application note discusses how to use the power management systems, provides use case examples, and shows real-time current measurement results for these use cases. A section on how to use the DDR memory controller to maintain the low power nature of your application is in this release. Also included is a discussion of the differences between power management features on the various microcontrollers, along with drivers demonstrating these low-power states.Tips are given for using each of the power modes. Power management methods discussed here do not include details on the clock generator module. Refer to the MCU reference manual for a description of the clock modes as well as the explanation of Multipurpose Clock Generator(MCG) acronyms. This application note focuses on the Power Management Controller (PMC), the Low Leakage Wakeup Unit (LLWU), the Reset Control Module (RCM), and the System Mode Controller (SMC).
