Input voltage on IO pins of WizWiki-w7500 and other 7500X chips

Hi, YegorS.

I’m sorry to mislead you.
W7500x can accept both 3.3V and 5V. but if you use 5V level, you can’t use ADC.
So i recommend you would use 3.3V level.(Not recommend using Max voltage)
Web page`s information will be changed.

I could not understand your second question.
If you follow datasheet`s characteristic, all W7500X chips work same under same electrical condition.

Please ask again, if my answer is not sufficient.

Thank you.

ADC is not available even at 3.3v level.

Thanks.
