Accuracy of MPC5674F internal temperature sensor

Question asked by YoungSeo LEE on Jun 11, 2017

dear NXP team, 

 

I am testing the temperature sensor function in MPC5674F using the EVB board.

 

I searched the community and downloaded the example code(Example_MP5674F-TSENS-Temperature_cal), 

 

I loaded the sample code on the target board and run it.


The measured TSEN_CODE value were changed between 26 and 32 degree. 

 

I think the deviation is very large, it is normal range?

 

i wanna know a normal error range. 

 

and, if the measured value is normal, it is difficult to use in my project . 

 

Is there a way to improve accuracy?
