RM46L430: Vibration level specifications in Industrial environments

Part Number: RM46L430

From the safety perspective, RM46x series micro controllers seems to be well stuffed. We have some queries on the performance under harsh environments:

1. When we use these micro controllers in control systems in harsh industrial environments how is the reliability of these micro controllers? Like for example, if they are used in ECU in automobile industry, typical high vibration environments, what could be the affect on the micro controller assembled on the PCB?

2. Is there any certificate for these micro controllers tested under these scenarios mainly from the vibration scenario?

3. What specifications do these micro controllers comply with under vibration environments?

4. The scenario might be different if  you use a BGA or QFN. What could be the choice among these for the RM46x for the automotive industry?

  • Hi Dharanidhar,

    There isn't any data or certification that we can provide from a safety perspective.

    It is a system level design problem and it involves not only the packaging but also your PCB material set, assembly process, and the stresses that your end system is subjected to. So it's really a problem that is outside of the scope of what we provide which is just component level safety data.

    TI does have generic (based on package family), quality & reliability information for packaging but this is different than 'functional safety'. Still it may be useful to look at these appnotes for some guidance.

    For the BGA package of the RM46 it is an 'nFBGA' type and the appnote is:

    There is some reliability info there but you need to decide if it applies or if you can draw any conclusions from it.

    You can look at this page to see what application reports are available:
