Questions about MPC5674F 5V power supply

Question asked by YoungSeo LEE on Jul 10, 2018

Dear NXP team,


I have one question related to a 5V power supply of MPC5674F.


If the ADC module in MPC5674F is not used by my application, can the MPC5674F operate normally even if 5V power is not supplied to the MPC5674F?


If the MPC5674F can operate normally without the 5V power supply, does the 5V VDDA pin remain floating(open)? Or do I need to connect a pull-up or pull-down resistor?


I will wait for your answer.
