Hello,
I am working on i.MX8m mini evk, I want to know the power supply for RTC. As per the document

@IMX8MMIEC.pdf in SNVS mode, there are two power supplies VDD_SNVS_0P8 and NVCC_SNVS_1P8 that are remains on to give power to rtc. So which one of from these is the power for RTC.

Thank you

Hi @Dhvani,

I hope you are doing well.

As mentioned in Table 67. i.MX 8M Mini 14 x 14 mm functional contact assignments in the datasheet, the power group of RTC is NVCC_SNVS_1P8.

Thanks & Regards,
