IWRL6432: IWRL6432 nRESET reboot

Ken Zhang

Part Number: IWRL6432

Hi Experts

Customer wish to trigger a reboot via nRESET while all power rails are still on.

What's the minimum time requirement for nRESET to be de-asserted to trigger a reboot?

Thanks

Hi Ken,

I would point the customer to the reset timing chart in the IWRL6432 datasheet here:

Hi Tim

From the chart, we can see that DC power could be shut down after nReset is asserted.

I did not find minimum time nReset should be kept low level before it could generate a reboot.

Thanks

Hi Ken,

I've found this in the current draft TRM:

Looks like the minimum time is 20 usec.
