RT1060 power control diagram and power up sequence

[guillaume_g]

the reference manual and the hardware development guide are clear on how to connect power if we want to use stand by mode and 32K768 clock.

if we didn't want to have low power mode can we simplify the power diagram as follow.

This power diagram from my understanding should satisfy power up sequence and hardware recommendation.

could you please confirm?

Hi @guillaume_g ,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Could you please confirm?
-- Yes, the simplified power supply design is available.
Have a great day,
TIC

I have a question if the VDD_SOC_IN (1.2V) is provided externally instead of the internal DCDC, switched by DCDC_PSWITCH with 1ms delay.
In this case, does the externally supplied 1.2V on VDD_SOC_IN also have to have a delay of 1ms?
Or is a 1ms delay not necessary in this case?
We use the MiMXRT1062DVJ6B in B-Revision (A1 silicon)

Hello,

same question here: custom design with i.MXRT117x and power-up sequence.

Is it fine to tie together VDD_SNVS_IN, VDD_LPSR_IN, DCDC_IN AND NVCC_XXXX ?

Thank you very much, best wishes.
