主要特點
參數類型

AiP8209 能够测量有功功率、无功功率、有功能量、无功能量，并能同时提供两路独立的有功功率和有效值、电压有效值、线频率、过零中断等，可以实现灵活的防窃电方案。
AiP8209支持全數字的增益、相位和offset校正。有功、無功電能脈沖分別從PF、QF管腳輸出。
AiP8209提供兩個串行接口SPI和RSIO，方便與外部MCU之間進行通信。其中RSIO爲銳能微專有的單線通訊接口，可以使用一根數據線實現雙向通訊。
AiP8209内部的電源監控电路可以保证上电和断电时芯片的可靠工作。

"What is that?" Allingham paused in the turning of the handle and stared, aghast, at his companion. There was no mistaking the significance of the remark, and it had been spoken in tones of strange tenderness. Rapidly there swept across the Doctor's mind a sensation of complete conviction. If there was any further proof required of the truth of Gregg's conjecture, surely it was expressed in this apparently insane and yet obviously sincere solicitude on the part of the Clockwork man for an inanimate machine? He recognised in the mechanism before him a member of his own species! Lawrence laid a hand on his friend's shoulder. So, after waiting for the reply of the gentleman whose business it was to give me this free pass, seeing that he could not make up his mind, I left the town without it. “As I live and breathe!” Mr. Everdail spoke gruffly, “I begin to wonder if you shouldn’t be the one to have ‘suspicious’ for a nickname. You have suspected Jeff, and me, and my friend who was with me, and Larsen, here, and his passenger—Captain Parks and now Mimi! It will be Miss Serena next!” Parliament, which had been prorogued for a few days on account of the demise of the king, assembled on the 18th of November. The king delivered a speech, composed by Lord Hardwicke, and revised by Pitt, and containing a passage, said to be inserted by himself, as follows:—"Born and educated in this country, I glory in the name of Briton!" In the addresses these words produced the most enthusiastic responses. "What a lustre," exclaimed the Lords, "doth it cast upon the name of Briton, when you, sir, are pleased to esteem it amongst your glories!" For the rest, the speech expressed the royal determination to prosecute the war with all vigour; praised the magnanimity and perseverance of his good brother, the King of Prussia; and recommended unanimity of action and opinion in Parliament. Nothing could appear more unanimous or more liberal than Parliament. After the song was over, he remained sitting, waiting for what had to come. The rumbling continued, and the room shook more strongly. For some seconds he waited, and then he was standing erect, because he could see. Then he was against the tree while Dara stood behind, waiting. He pressed himself against the bark and he felt himself becoming part of Great Root Tree, becoming the tree itself; and this lasted for all time and no time, and he was separated from it and saw Dara come to where he had pressed, and move delicately and then fiercely upon the bark; then he saw nothing but heard her breathing faster and faster, and all sound stopped ... there was a long silence ... and then her breathing began again, very slowly, very slowly. O why, because brothers and friends all have left me, At last they reached the lane by Eggs Hole Cottage, which with shimmering star-washed front looked towards the south. He stopped, and she slid to the ground. Then suddenly the words came. Well, he had taken it now—it was too late to give it back. Besides, why should he not have it? Those ten pounds probably did not mean much to the Squire, but they meant all things to him and Bessie. He could marry her now. He could take her away, find work on some distant farm, and comfortably set up house. The possibilities of ten pounds were unlimited—at all events they could give him all he asked of life. "Alice."
