MSP430F5328-EP: MTBF Parameters for MSP430F5328-EP for calculation according MIL-HDBK-217F-Notice2

Part Number: MSP430F5328-EP

Hi,

I have to do reliability calculation for a design with several TI-products according MIL-HDBK-217F-Notice2.

As mentioned in another post, the MTBF values given by TI follow the JEDEC-STD. So the values are not comparable to MIL calculated values.

How TI calculate MTBF? - Post in E2E

Anyway, could you provide the "Die complexity Failure Rate C1" value. This is calculated from the number of gates / number of transistors in the component.

I need this information for these products:

MSP430F5328TRGCTEP
TPS3808G01MDBVTEP
TPS71501MDCKREP

Thank you and Best Regards,

Alessandro

    Hello Alessandro,

    TI is unable to support MIL-HDBK-217.  Please note that transistor counts are TI proprietary information and not disclosed.   FIT rates are calculated and reported per JEDEC JESD85 “Methods for Calculating Failure Rates in Units of FITs”.   The majority of our defense customers are able to use the raw data provided in the online FIT reports to perform related reliability calculations. 

    In addition, TI’s goal is to have an EP qualification report available in the respective product folder under the “Technical documents” tab in the "Radiation & Reliability reports section for each EP device.
