TM4C1290NCPDT: tpw value for BOR

Linda Zhang84708

Part Number: TM4C1290NCPDT

Hello Champs,

In TM4C1290 datasheet Figure 26-8, there is no typical and maximum description of tpw value for BOR.

Would you please kindly help? Thanks!

Best Regards,

Linda

    Hello Linda,

    Unfortunately that is the extent of the data available for that specification. I am not sure how typical or maximum time would help anyways, as for this you'd want to know the shortest pulse which could trigger a BOR. Knowing longer pulses doesn't, to me, seem to add much value.

    Maybe we can help clarify some other points regarding it if the concern regarding the data is made a bit more clear?

    Hello Jacobi,

    Thank you for your reply.

    Customer needed to know the shortest pulse which could trigger a BOR. Would you please kindly help again? 

    Best Regards,

    Linda

    Hello Linda,

    I am not sure what else to offer beyond the Figure you referenced. Can the customer explain what is unclear about the relationship between the voltage level and the duration of the pulse to trigger the BOR that is highlighted in Figure 26-8?
