Kinetis和ColdFire+ MCU功耗管理(英文)
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).
