Hi
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?
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.
