平衡MCU的性能和功耗与集成功能
开发商有一段时间，低功耗MCU功能运行状态下，关闭外设甚至核心本身来降低系统功耗的要求。然而，对于一些应用程序，开发人员需要更多的直接控制电源利用率，以确保系统的部分仍然供电，以满足关键功能要求。
设计师过去使用独立的电源管理设备来构建精确的功率控制。相反，模拟设备aducm3029单片机提供了一个可以帮助开发人员更容易地实现最大的性能而在内置的传感器数据采集，设计功耗最小化集成的解决方案，服饰，和物联网等互联网（物联网）的应用。
MCU’s addressing power management
For low-power designs， engineers can find a wide range of advanced MCUs designed with power saving opTIons. Devices targeTIng power sensiTIve applicaTIons routinely feature capabilities such as frequency scaling that allow engineers to trade performance for reduced power.
Typically， low-power modes offer graduated power reduction by shutting down more and more MCU subsystems until only the minimal circuitry required to wake the MCU remains operational. As a further refinement for power management， ultra-low-power MCUs add special operating modes that separately manage power to the device’s core and its peripherals. Even in these cases， these special modes sometimes shut down peripherals as a group， or use automated mechanisms that grant the developer little control over the details of power allocation.
