TMS320F28020: Automotive ASIL B/C

Part Number: TMS320F28020

Hi,

 I would like to know if we are doing any activity to qualify our devices to ASIL B/C for any of the C2000 family, in particular for F2802x/2803x .

Thanks

Umberto

    Both F2802x and F2803x are developed using TI’s QM (Quality Managed) ISO-9001/IATF 16949 compliant product development methodology.

     

    Additionally we have the following support available for these devices

     

    1. A free TI (SDO – Compiler Team’s) release validation based Compiler qualification kit that supports both the C28x and CLA compilers

      http://www.ti.com/tool/safeti_cqkit

    2. An (also free) SafeTI Software package (available in source) certified by UL (to UL 1998 class 1) and VDE (to IEC 60730 Class B) that helps system integrators design for safety compliant end applications.

    • This SW package includes ready to run application examples that demonstrate how to create power-on-self-test (POST) and periodic-self-test (PEST)

    • This SW package also comes with a user guide and a Safety Manual and may be downloaded from:

    http://www.ti.com/tool/iec60730swpackages

    1. And finally, TI can also provide (only under SafeTI-NDA) a quantitative FMEDA for F2802x and F2803x that is based on the following assumptions:

    • Analog macros soft FIT is not considered in the FMEDA since TI did not have information on the contribution of analog components (e.g. Flash, ADC, etc.) to chip FIT.

      • Package FIT and IO FIT are also not considered.

    • Base Failure Rate (BFR) due to hard failures in 180nm embedded Flash technology (F05) was not available. Hence BFR of the130nm eFlash (F035) node is used in the computation.

      • According to the literature, BFR increases with technology scaling and hence the data will be pessimistic.

    • BFR due to soft errors in F05 is calculated based on TI’s proprietary calculator.

      • The value is different for flip-flops and memory elements and hence calculated separately.

    • Contribution of on-demand hardware diagnostics (example CPUBIST for memory, STL for core etc.) were not considered.

      • The calculated value will be hence pessimistic and realistic values can be obtained by including coverage of on-demand diagnostic measures.

     

    Last but not least all the efforts for ASIL-B/C device certification according to ISO 26262 is currently focused on the F28x7x and F28004x device families.

    We do not have any plans to certify F2802x or F2803x devices to ISO 26262.

    However, customers may be able to use the support (described above) to certify their systems based on F2802x/F2803x to meet ASIL-B/C (at the system level) according to ISO 26262
