5M570ZT144A5 and 5M570ZT144I5

Hello,

 

Due to chip shortages we are trying to move one of our products from using 5M570ZT144A5 to 5M570ZT144I5 as it seems more available. However, given that our product was certified with 5M570ZT144A5, our client is asking questions about the specific differences between the two chips. From the datasheet the only difference I can find is the temperature rating but we wonder if the automotive version is subject to any extra checks, different controlled assembly line, etc., or rather are the two chips identical but checked at the end of the assembly line and classified accordingly? Some information on this regard would be much appreciated.

 

Also, if we were to exceed the maximum operating temperature (100 degrees for the industrial version), what would be the expected behaviour? as in, if we run 110 degrees, would it just break and stop working? or rather it would have a decrease in speed performance? or reliability?

Hi,


Apologize for the delay in response.


As for the differences, it is the same as you read in the datasheet. No other differences.


The FPGA might be broken or not functioning if it is used beyond the exceeded temperature.

Aiman

Hi,


The following rules generally apply wrt bit-stream compatibility where re-compilation is not necessary :

  • You can migrate to the same density device with a fabric speed grade that is faster, i.e. a bitstream targeting speed grade 8 can be configured onto speed grade 7 or speed grade 6 part.
  • You can migrate to the same density device with an operating temperature that supports a wider temperature range, i.e. a bitstream targeting commercial grade temperature can be configured onto industrial grade or automotive grade part. 

If using an Industrial part with the same or faster speed grade and if operating the device in the Industrial operating temperature range, then they should be able to use the same bit-steam without recompiling.


We would also recommend you to follow the maximum operating temperature as stated in Intel's document as it was tested and proven working. Intel will not be responsible if the device damaged when using exceeded temperature (>100 degrees).

Aiman

Hi Aiman,

 

Can you help?

Hi Aiman,

 

Thanks for the quick reply. Regardless of having to re-compile the program or not, could you provide any information about the devices (5M570ZT144A5 and 5M570ZT144I5) temperature grade? Is there any other difference between the two? specially in terms of reliability? 

 

Could you provide any information of what behaviour we would expect if we exceeded the temperature? (Intel will not be responsible but it would help our case to know if there is any information available)
