Discussion on the Influence of static electricity on arm Single-Chip Microcomputer

 

Summary:

 

MSP430 single-chip microcomputer 8 kV electrostatic dead machine,

 

Arm will not crash much, but static electricity is easy to penetrate into arm's Io,

 

Then, the I/O short-circuit chip is exposed to heat. When the chip is damaged, some chips are cracked,

 

However, it can be restored after power failure,

 

No external guard is used,

 

Reset after static electricity is not easy to enable, must be powered on,

 

According to the Internet, EMI conductive paint is sprayed inside the plastic casing, but the situation is mitigated, but it will still crash,

 

We use the all-metal shell, the same will appear,

 

Generally, it is not safe and it does not need to be so high. The industry's highest level is,

 

If I have time to test it, other ARM chips and key lab boards have no protective devices, which are easy to penetrate,

 

The nxp esd device is also used in our products. The integrated TVS has a general effect,

 

The above personal opinions are still to be tested. If there are better test results, they will be published,
