MSP430FR5969: MSP430FRx Parts Family Process and Qualification

William Ng
Prodigy 30 points
Part Number: MSP430FR5969

Tool/software:

My team is developing a system that includes multiple variants of MSP430FRx microcontrollers. We are working on environmental testing/qualification of our candidate components which includes several types of MSP430FRx controllers.

  1. Are all MSP430FRx microcontrollers fabricated on the same semiconductor process and line? I do not need the details of the fabrication recipe itself, but knowing if the dies are equal in process will give us confidence that these parts will behave as expected in similar conditions.
  2. Do all MSP430FRx's go through the same environmental testing/qualification within TI or is there a different process between different variants of the MSP430FRx?

    Hello William,

    1. I believe all MSP430FRxx do currently get manufactured in the exact same fab, although I can't guarantee that will always the case.  Due to business needs, it's always possible that we move it or split it to other fabs in the future.  Before doing so, we always qualify the fab for the device so that we can stay consistent with our quality.

    2.  Overall, all devices do go through TI's overall standard testing and qualifications from a quality/reliability stand point.  Things like lifetime aging testing, FIT rates, ect.  You can find more and look up devices here: https://www.ti.com/support-quality/quality-reliability.html  

    Those tests are usually performed on a large set of devices and limits set statistically from that data.  As part of manufactoring/production, each device will go through a test program at different stages of production, checking functionality, limits, and performing any needed per device calibration.  These manufacturing test programs can vary from family to family, especially as features/functionality also varies. 

    Hope this was helpful.
