PIC XLP開發(fā)板演示了如何低你可以走

　　廣泛的睡眠模式使應用程序在功率級空閑，所以很難測量。

　　從歷史上看，微控制器廠商的競爭在很大程度上是由“更快更好”的理念主導的。終于打電墻-在穆爾Law和歐姆定律的共同努力下，半導體廠商都在競爭看誰能最低功耗MCU的惡意。”“低功率”現(xiàn)在已經(jīng)被“超低功率”所取代。當涉及到低功率時，底部的競爭正在升溫。

　　嵌入式開發(fā)人員目前有一個廣泛的非常能干的低功耗MCU的選擇。這是一件尷尬的事，由沖突（如果仔細合格）聲稱，MCU有活性最低，待機、睡眠、深度睡眠、或其他操作特性。事實上，工藝技術的擴散，電源管理技術和經(jīng)營模式已經(jīng)很難做一個蘋果對蘋果比較不同的MCU只看他們的數(shù)據(jù)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.
