AM2431: Magnetic immunity testing 600mT

Ambroise

I have not heard of such a test. However, I'll make some inquiries and get back to you, probably early next week.

Is there a specific EMC standard you are try to meet?

Hi Paul,

There is no EMC test for this specific issue. This is a test demanded by the utilities to prevent users of manipulating the processor with a strong magnet (600mT at zero distance).

Hello Ambroise

Thank you.

Looks like this is an system level and use case specific testing.

Example:

See below

We may not have similar tests performed for the processor or the EVM.

Hi Sreenivasa,

As mentioned before, this is not a system level / use case specific test. The end-customers are expecting some form of confirmation that the individual ICs are not susceptible to strong magnetic fields.

Hello Ambroise

Thank you.

I am not sure if there is any tests we do on the IC level or board level.

Let me check internally and update.

Hello Ambroise

The tests we do is listed in the below EU conformance report.

Hello Ambroise

Amy thoughts if you received similar report from any of the other PLs?

Hi Sreenivasa, 
We are also checking for the AM261x, but it's the first time we received such a request.

Hello Ambroise

Thank you.

Let me check one more time internally and update.

FYI, we have not previously support similar query.
