MIMXRT1176AVM8A internal dc dc operating frequency

I will use internal dc dc of MIMXRT1176AVM8A without PMIC.

8 in the processor code and as far as I understood from the datasheet, the nominal core frequency of the 800 Mhz processor..

Can I go to higher frequencies if I need it?

Can I use this processor in a 1 Ghz application(Automotive)? If I can, what would be the differences in terms of temperature?

Hi,

Thank you so much for your interest in our products and for using our community.

The part that you mention can only operate up to 800 MHz.

Have a nice day!

hi @_Leo_

Is the frequency you are talking about internal dc dc operating frequency?

Can I run internal dc dc with 800 mhz?

The on-chip DC-DC regulator of the processor is suitable for consumer and industrial applications up to 105 °C. The part that you are using is for automotive applications, in this case, the core platform power consumption may exceed the internal DC-DC capacity as the Tj is increased to 125 °C. In such cases, use RT1170 with NXP PF5020 PMIC.
