S32k3 pin current and total power disspation

[mogilipuri_harish]

hello team,

kindly help to calculate the power and load current calculations for S32k3 series micro controller. 

what is minimum and maximum input supply voltages of s32k3 series micro controller?

hello daniel,

1.how to choose VDD_HV_A = 3.3V or 5V, VDD_HV_B = 3.3V or 5V??

2. how we will know which gpio pins connected to VDD_HV_A and VDD_HV_B??

Hello @mogilipuri_harish,

1.

Depends on the application requirements.

2.

This can be found in the IOMUX.xlsx files that are attached to the RM.

hello daniel

1.how to configure the GPIO's 5V logic level? is it just we need to connect 5V supply to VDD_HV_A or do we need to any configuration??

2. how to configure the PWM output signals? we need to configure the PWM output signal with 75% duty cycle with 16Khz .

Hello @mogilipuri_harish,

1.

Yes, just connect the VDD_HV_A to 5V source.

Refer to S32K3 Hardware Design guidelines in

S32K3 MCUs for General Purpose – Hardware Design Package

https://www.nxp.com/products/processors-and-microcontrollers/s32-automotive-platform/s32k-auto-gener...

2.

Please create a new thread for PWM.

Regards,

Daniel

for question no 2 which pin we can configure for this operation??

[danielmartynek]

Hello @mogilipuri_harish,

Certain EMIOS pins, for example.

You can refer to RTD example.

If you need more delails, please create a new thread, this is not related to current consumtion / dissipation.

Hello @mogilipuri_harish,

There is S32K Power Estimation Tool (PET)

https://www.nxp.com/design/automotive-software-and-tools/s32k-power-estimation-tool-pet:S32K-PET

All the supply voltage specifications can be found in the datasheet

https://www.nxp.com/docs/en/data-sheet/S32K3xxDS.pdf

Chapter 5 General.

hi daniel,

we are using VDD_HV_A = 5V

as per the datasheet max = 5.5V  typ = 5V min = 2.97V

the voltage max tolerance is 10% and minimum tolerance is  40.6%

VDD_HV_B = 3.3V

as per the datasheet max = 5.5V  typ = 3.3V min = 2.97V

the voltage max tolerance is 66% and minimum tolerance is  10%

this means this much tolerance will be there??

Hi @mogilipuri_harish,

Yes, that is correct.

The lower limit is becasue of the Low Voltage Reset + some margin.

Regards,

Daniel
