Part Number: TM4C1294KCPDT

Hi Experts,

Is there any specification of the timing from power-on to deasserting RST(external reset) pin?

Hi,

What is specified in the datasheet is the de-assertion of digital POR to the deassertion of internal Reset. Please refer to the datasheet for details.

The Digital POR is is only released when the POR has deasserted and all of the Power-OK monitors for each of the supplies indicate that power levels are in operational ranges.

Hi Charles,

The spec what we want to know is below.

I looked the datasheet again. Since R2 is defined as a delay from several reset sources to the release of internal reset, I think the spec R4 or Trstmin should be enough for this inquiry.

How do you think?
