PIC16F18877在较低的HFINTOSC速度下真的是低功耗吗？

您好，如果您使用3.3V电源，更喜欢“LF”版本，它没有内部调节器（PIC16LF1887）。您可以使用Quest-HPC板轻松地进行这些电流测量（您甚至可以将PIC16LF1887放在该套件上）。我为最近的PIC16或PIC18做这个。这个套件具有片上调试器（不需要外部PACTIT3）。使用MCC插件更快地生成代码。如果你有经验，一天之内你可以做各种功率测量。

    Hi,
If you use 3.3V power supply, prefer the "LF" version which has no internal regulator ( PIC16LF18877 ).
You could do these current measurements easily using the Curiosity HPC board (you can even put the PIC16LF18877 on that kit). I do this for recent PIC16 or PIC18.
This kit has on chip debugger (no need for external Pickit3).
Use MCC plugin to generate code faster. If you are experienced, within one day you can do various power measurements 
Regards
 

谢谢你的回复。也许我应该说：16HF18XXX或16LF15XXX或16LF19XXX @ 1兆赫，因为它们都有相同的HFIFToC设计。我不欢迎想到必须购买一个特殊的董事会和混乱的配置和设置，以获得我认为是基本规格的寿司。在数据表中找到了大多数其他PIC MCU（和其他MCU），为什么不为16F1XXXX家庭？（功耗）@ 500千赫，1兆赫，4兆赫，8兆赫。所有的数据表都对此保持沉默。我所做的——也许应该更清楚——是一个基于数据表的高级评估。我喜欢16F1XXXX家庭的各种铃声和口哨，但是需要知道更多关于低于16 MHz的功耗。用160F1XXXX或16LF1XXXX在1兆赫（或500千赫）使用HFIFTROC的电力消耗，我将非常感激…

    Thank you for your reply. Perhaps I should have stated: 16LF18xxx or 16LF15xxx or 16LF19xxx @ 1 MHz using the HFINTOSC since they all have the same HFINTOSC design.
 
I do not welcome the thought of having to buy a special board and messing around with configuration and setup to get what I consider to be basic specs that should be in the datasheet ;-(  Power consumption @ 500 kHz, 1 MHz, 4 MHz, and 8 MHz are found in the datasheets for most other PIC MCUs (and other MCUs), why not for the 16F1xxxx families? All their datasheets are silent on this. 
 
What I am doing---and perhaps should have been clearer about it---is a high-level, datasheet-based initial assessment. 
 
I like the various bells and whistles the 16F1xxxx families have but need to know more about power consumption below 16 MHz.
 
So, if someone knows the power consumption of any 16F1xxxx or 16LF1xxxx at 1 MHz (or 500 kHz) using the HFINTOSC, I would be most grateful....
 
 
 
 

我不知道，也许这是一个疯狂的想法，但你有没有考虑直接问微芯片？

    I don't know and maybe this is a wild idea but have you considered asking Microchip directly?
