Hi Ben,

This is the factory memory region. If customer is reading several devices of same type, then the values should be the same, or am I not understanding the customer's question?

Hi Dennis,

Shouldn't one chip correspond to one ID?

Best Regards,

Hi Ben,

Sorry for the late response. Looking the DEVICEID register, all MSPM0L1306 will have same REV, PARTNUM and MANUFACTURER. The only field that will change over time is if there is a silicon spin from say revA to revB. Otherwise, all other fields will be the same from part to part.

Does this help, or am I still not understanding what the customer is asking?
