PFE power consumption

[Daniel_Wax]

Im trying to help a customer determine the power consumption if only one M7 pair and the PFE are enabled.  All A53s are shut down and the other two M7s are shut down.  All other peripherals not being used.  Is there are Power consumption info on the PFE?

Please take a look at the applications notes AN13299 (S32G2 Power Estimations) and AN12952 (S32Gx Power Saving Techniques), these relates to power consumptions. In particular the first one provides dynamic power numbers for the cores and PFE modules.

Thanks.  I now see a 320mW for PFE in AN13299.  AN12952 does not exist anywhere I can see.  Not on the public site and not in DOCSTORE

It is strange... The AN12952 can be found among other app notes on the S32G2 home page:

@Bulat do you think this looks correct for maximum power consumption looks around 6W(max core:4.5W + IOs: ~1.5W) and it might need cooling system for processor.  Do any customers think that cooling might be needed?  Is the guess at S32G3 in the ballpark?

	power (mW)	remark
S32G274	4500

4  additional A53	260	130 * 2 dynamic power
