DP83825I: RST_N specification

Part Number: DP83825I

Tool/software:

Hi, all

I have three questions about the data sheet that was changed from Rev A to Rev B.

The data sheet explains that RST_N is connected to AVDD (3.3V) instead of VDDIO.
1. I think this is a very important change, but it is not mentioned in the Revision History. Why is that?
2. Please tell me the specifications for the RST_N pin threshold voltages, VIH and VIL.
3. Please tell me the value of the internal pull-up resistor for the RST_N pin.

Thanks in advance.
Regards,
Toshi

I apologize for the inconvenience this caused. We will fix this with the new revision that is planned to come out by the end of the year.

VIH is 1.7V
VIL is 0.8V

It is 10k.

Please let me know if you have any other questions.
