MSP430FR5041: Highly Magnetic Interference Environment

I don't know about this one, but some have an -NM on the part number which means non-magnetic.

Hi,

I do not think the MSP430FR5041 can support a Highly Magnetic Interference Environment.

Best regards,

Magnetic coupling is to low impedance loops. With coupling proportional to loop area. ICs have small loops so little coupling. Unless of course you create loops on the PCB.

The digital sections of the MCU require a lot to upset.

So as with everything, use careful design to minimize susceptibility and add mu-metal shielding if that proves insufficient.
