一种适用于模拟信号读取的装置

不确定价格，但是一些PIC10也应该有ADC的功能。



以下为原文

Not sure about price, but some PIC10 should feature an ADC as well.

PIC12F675的单机数量仅为0.95美元，在100台PC机上只有0.91美元，具有4位10位ADC。PIC10F220是单价0.48美元，100台PC 0.41美元，有3位8位ADC。PIC12LF1552为单0.70元0.70美元，0.52台PC 0.52美元，并具有0.52位ADC。似乎没有PIC12F1552，所以电源限制为3.6伏。



以下为原文

The PIC12F675is only $0.95in single quantity, $0.91in 100 pc, and has 4 10-bitADCs.

The PIC10F220is $0.48in single quantity, $0.41in 100 pc, and has 3 8-bitADCs.

The PIC12LF1552is $0.70in single quantity, $0.52in 100 pc, and has 5 10-bitADCs. There does not seem to be a PIC12 F1552, so power supply limited to 3.6 V.

我想知道你想用电流传感器读取的模拟值做什么？它可能有相当的影响，PIC可能是合适的。



以下为原文

I wonder what you intend to do with the analog value read from the current sensor ?
It may have quite an effect on which PIC might be suitable.

我很好奇为什么你使用这个部分（ACS712）。这是一次性的实验项目还是生产设计？你有没有想要买另一个零件的那种？我问，因为Allegro很清楚，一年多以前，这部分不是为了新的设计，不会卖给新客户。AlelGo推荐ACS723用于新设计/新客户。



以下为原文

I'm curious why you are using this part (ACS712).

Is this a one-off lab project or a production design?

Do you have one that you want to use without having to buy another part?

I ask because Allegro is very clear that as of more than an year ago this part is not for new design and won't be sold to new customers. Allegro is recommending the ACS723 for new designs/new customers.

非常感谢你们所有人提供这些有用的信息。

Many many thanks to all of you for providing this much of useful information.

嗨，我认为PIC12F675已经过时了，是一个很难开发的实验设备。它不能用MPLAB进行调试，而不需要用昂贵的调试适配器替换微控制器。如果你已经有PIC12F675，你可以使用它，但是如果它不是免费的，就不要再买了。PIC器件在14引脚或20引脚封装可能是更灵活的发展。PIC微控制器在8引脚封装，14引脚封装，20引脚封装有电源和编程/调试引脚在同一个地方，所以可以使用相同的开发板，或者你可以使用一个电路板Expe如果您购买，您可以查找PIC16F1829、PIC16F1828、PIC16F1825、PIC16F1824、PIC16F1823、PIC12F1822或PIC12F1840，这些设备都是一个具有相同处理器和外围设备的家庭，甚至8PIN封装中的设备也可以与MPLAB调试器一起使用。该系列可用于家庭中其他设备的小变化。调试需要5个引脚用于电源和调试信号，因此只有3个引脚可自由编程使用。或者关于任何PIC16或PIC12器件，在字符F之后首先具有数字1，如PIC12F1XXX或PIC16F1XXX或PIC16F1XXXXE.G.PIC12F。1501或PIC12F1612IF为电池供电的设备设计3 V电源，您可能会想到PIC12LF…在较小的表面安装封装中，如UDFN或SOIC，器件的价格比PDIP低，如果您能处理小引脚间距。迈西尔



以下为原文

Hi,
I think PIC12F675 is obsolete, and a awkward device for experimentation and development.
It cannot be debugged with MPLAB , without replacing the microcontroller with a expensive debug adapter.

If you have PIC12F675 already, you may of cource use it, but don't buy any more, if it isn't nearly free.
PIC devices in 14 pin or 20 pin package may be much more flexible for development.
PIC microcontrollers in 8 pin package, 14 pin package, and 20 pin Package have Power supply and Programming/Debugging pins in the same place, so may use the same development board,
or you may use a breadboard for experiments.

If you buy, you may look for PIC16F1829, PIC16F1828, PIC16F1825, PIC16F1824, PIC16F1823,
PIC12F1822or PIC12F1840.
These devices are all in a family with the same processor and peripherals,
and even the device in 8-pin package may be used with MPLAB Debugger.
Program developed for one device in the family, may be used for other devices in the family with small changes.
Debugging need 5 pins for power and debugging signals, so only 3 pins are free for program use.

Or about any PIC16 or PIC12 device with digit 1 first after character F, like PIC12F1xxx or PIC16F1xxx or PIC16F1xxxx
E.g. PIC12F1501 or PIC12F1612
If designing for battery powered devices with 3 V power supply, you may think about PIC12LF... devices.

Devices in smaller surface mount packages, like UDFN or SOIC, have lower price than PDIP, if you can handle the small pin spacing.
