MSPM0G3107: Flash memory when do erase operation

Kenley
Intellectual 1825 points

Part Number: MSPM0G3107

Hi team,

 

My customer told me that erase is required when rewriting Flash parameters, etc. 

So they implemented as follows. 

Here, only 1kB (sector size) is preceded by the specified address.

  1. Is it true that the Flash region will be erased by the above command? 
    In the unlikely event that the power to the microcomputer is lost during this erase,
    Is there any possibility that other Flash regions will be affected?
    Is the scope of influence only the sector area to be erased, or is it possible to affect the entire Flash? 
  2. If the power is cut during sector erase, the program area is affected. 
    They are concerned that the software will not start.
    How much does the MSPM0G3107 Flash guarantee? 

Best regards,

Kenley

    Yes, that is true.

    The impact of the scope is limited to the sector being erased only. Other Flash sectors/regions will not be affected.

    If the application code gets corrupted, it is possible that it may not behave as expected. With regard to Flash guarantee, here are the Flash memory characteristics:
