MSP430F6779A: Strong DC Magnetic effect

S Ch

Part Number: MSP430F6779A

Tool/software:

Hello TI team, I have 2 questions as below,

1.Can Strong DC Magnetic (more than 0.4 tesla) affect to cause MCU internal short circuit? if not any affect to MCU problem?

2.Is there any specification for maximum DC Magnetic immunity of MCU? How much tesla?

If the DC magnetic is static, even it is strong, it should be fine. If it changing fast, it will be matter, but unfortunately we do not have such specific test data so far.

How does affect to MCU? Does it affect to IC wire bonding?

I just affect the inductor circuits in the MCU as you know the fast change magnetic may cause high voltage on inductor circuits that may damage the chip.
