低功耗设计基础:如何为嵌入式系统选择最佳低功耗MCU
设计一个低功耗的微控制器并不容易,也不能为您特定的嵌入式设计选择合适的微控制器。许多特定于应用程序的考虑,使得比较MCU规格表具有挑战性。本文分析了竞争性MCU替代方案的功率效率分析中应考虑的关键因素。
节约能源对环境有利,对钱袋更方便。提高能源效率的诸多好处已经得到了充分的证明:为消费者降低电费,降低公用事业的负担,降低电子产品的拥有成本,减少填埋场丢弃的废旧电池。
随着电子设备的使用几乎渗透到我们生活的各个方面,降低功耗必须从半导体水平开始。在芯片级设计的节能技术具有深远的影响。尤其是关于微控制器(MCU)作为在今天的多数电子设备的智能引擎
From a systems architecture perspecTIve, the challenge of idenTIfying which MCUs truly are “low-power” requires designers to navigate through the myriad claims made by various semiconductor vendors. Because of the different (and often confusing) metrics used by vendors, this is not a simple task.
Let‘s take a closer look at the key factors that should be considered when analyzing the power efficiency of compeTITIve MCU alternatives.
At a basic level, MCU power consumption can be defined as the sum of the following:
Total power consumed = Active mode power + Standby (sleep) mode power
