PIC16F87A能支持模拟引脚的5.6V吗？

嗨，检查你的图片的数据表结束时的电气规格，你会发现这个信息

    Hi,
check the electrical specifications at the end of the datasheet of your PIC, you will find this information

…将是“不”



      以下为原文

    ...which will be "no"

我真希望这是一个试题。

    I do hope this is an exam question

实际上，PIC16F87在VDD上相对于VSS具有绝对最大的7.5伏电压。而且大多数引脚的电压限制在VDD+0.3V，所以如果电源电压为6V左右，ADC可能能够容忍5.6V。最大推荐电源是5.5V，所以在这种情况下5.6V就可以了。然而，ADC在该输入电压上可能不是线性的。PIC18F2550系列也容忍7.5V，而新设备如PIC16F1455仅限于65.V。

    Actually, the PIC16F877 has an absolute maximum of 7.5 volts on Vdd with respect to Vss. And the voltage on most pins is limited to Vdd+0.3V. So the ADC may be able to tolerate 5.6V if the supply voltage is 6V or so. Maximum recommended supply is 5.5V, so in that case 5.6V would be OK. However, the ADC might not be linear at that input voltage. The PIC18F2550 family also tolerates 7.5V, while newer devices such as PIC16F1455 are limited to 6.5V.
