Hi,
I will like to known what will be the better voltage to apply on VDD_SOC on our board IMX943. On your EVK, you have put 0.92V. On power file, it is somtime 0.85 or 0.9V.
According to available NXP documentation, VDD_SOC is associated with different SoC driving modes. Typical values are:
0.9V (Over-drive mode)
0.85V (Nominal mode)
0.8V (Low-power mode)
https://docs.nxp.com/bundle/AN14935/page/topics/soc_driving_mode.html
On the EVK platform, measurements show that VDD_SOC can be around 0.92V under certain operating conditions.
As i.MX943 is still in preproduction, final recommended values are defined in the datasheet under NDA.
For board design, you need contact nxp marketing team to get further support.
