　　广泛的睡眠模式使应用程序在功率级空闲，所以很难测量。

　　从历史上看，微控制器厂商的竞争在很大程度上是由“更快更好”的理念主导的。终于打电墙-在穆尔Law和欧姆定律的共同努力下，半导体厂商都在竞争看谁能最低功耗MCU的恶意。”“低功率”现在已经被“超低功率”所取代。当涉及到低功率时，底部的竞争正在升温。

　　嵌入式开发人员目前有一个广泛的非常能干的低功耗MCU的选择。这是一件尴尬的事，由冲突（如果仔细合格）声称，MCU有活性最低，待机、睡眠、深度睡眠、或其他操作特性。事实上，工艺技术的扩散，电源管理技术和经营模式已经很难做一个苹果对苹果比较不同的MCU只看他们的数据表。

　　Embedded developers are increasingly utilizing evaluation and development boards to test their application code on different MCU platforms. This article will take a hands-on look at Microchip‘s XLP 16-bit Development Board （see Figure 1）， which is designed to showcase the numerous software-selectable， low-power operating modes for its nanoWatt XLP eXtreme Low Power MCUs — in this case the 16-bit PIC24F16KA102. The board and its demonstration program — accompanied by well commented C source code — makes it easy to explore both the parameters and the trade-offs involved in utilizing various power-down modes.
