IWR6843: Device wake-up sequence

Kei

Part Number: IWR6843

Tool/software:

Hello,

The datasheet of IWR6843 indicates that the device wake-up sequence is shown in the figure below.
Do you have any specifications regarding the delay time between these four power rails?

"VDDIN, VIN_SRAM, VNWA"
"VIOIN_18, VIN18_CLK, VIOIN_18DIFF, VIN18_BB"
"VIN_13RF1, VIN_13RF2"
"VIOIN"

Hi Kei,

There are no delay time specifications for the power rails. We need to make sure all the power rails are stable before the NRESET release, the order and delay between the power supply signals are not fixed.

Hi Ankit,

Thank you for your answer. I understand.

Are there any plans to set specification in the future? Will the order of power supply still be flexible?

Kei

Hi Kei,

There are no plans currently to set specifications for order of power supply and delay between them as power supply can also supplied externally over connectors. To make the wake up more flexible we only check if the power supplies are stable at the time of reset release.
