XIO2001: Ask for PRST Timing Waveforms

Ken Hashi

Part Number: XIO2001

Hello

I would like to know about "Figure 8. PRST Timing Waveforms" of XIO2001.
Data sheet (SCPS 212 I) It is the content written in Figure 8 on page 25.

What is meant by "tw" here and how many values?

What is the value of "tsu" here means?

Regaeds.

Hello K-hashi,

The "tsu" is the time that the clk needs to be stable before to rise PRST. this value is 100us

Hello Roberto,

Thank you for your reply.
Does your explanation indicate "/ PERST" of the input signal?
Figure 8 in the data sheet describes the output signal "/ PRST".

Which one is correct?
In your diagram "/ PERST" is written, and your sentence is confused because it is written "/ PRST".

Best regards,
k-hashi

Hello Roberto

I think that the figure shown in your answer is Figure 4 in Datasheet P.22.

Please tell me about figure 8 on datasheet P.25.

Regards.
