i.MXRT1050 NVCC_GPIO

[woo-suklee]

Hi,

Currently, I'm designing i.MXRT1050 application and have a question on the supply voltage.

NVCC_GPIO
According to IMXRT1050CEC.pdf, Table 9. Operating ranges, NVCC GPIO supply seems to be ok with 1.8V.
However, MIMXRT1050HDUG.pdf, Table 1. Power domains specify NVCC_GPIO with 3.3V only.
Does anyone have any idea which one is correct?
I'd like to have NVCC_GPIO with 1.8V supply. Will that be fine?

Thanks and Regards,

WS

Hi igorpadykov,

Thanks for the quick reply!

I'll have all NVCC_XX supplied with 1.8V as you confirmed.
Some of the specifications on i.MXRT1050 varies across each documentations, by the way.

Thanks and Regards,
WS

Hi Woo-Suk

you are right, latest rev.1.3 datasheet changed these specs,

so NVCC_GPIO is only 3 to 3.6V (and NOT 1.8V).
