TMS320F28379D: Inquiry Regarding Safety and Performance Limitations of TMS320F28379D for High-Power DAL-B Motor Control Applications

 Dear TI Support Team,

 

I am currently evaluating the TMS320F28379D for use in high-power motor control applications (e.g., 64 kW BLDC drives with DAL-B/DO-178C safety requirements). During the assessment, I encountered a few technical limitations that may impact its suitability for safety-critical aerospace and e-mobility systems.

 

Key Points of Concern:

  1. Lack of Lockstep Architecture:
    • While TMS320F28379D supports dual-core operation, it does not offer native hardware lockstep for functional safety use cases.
    • Does TI offer any hardware or software-based redundancy solutions for meeting DAL-B requirements?
  2. PWM & ADC Synchronization:
    • ePWM and HRPWM provide excellent resolution, but I would like to confirm whether there is native support for high-speed ADCs with deterministic latency and tight PWM-ADC sync for FOC in high-performance systems.
  3. Simulink & Safety Toolchain:
    • We appreciate the native Simulink support provided by TI. For DAL-B compliance, does TI offer tool qualification kits, safety lifecycle documentation, or recommended workflows for integration into certified toolchains?
  4. Functional Safety Documentation:
    • Although a Functional Safety Manual is available, could you clarify if TI provides safety libraries, runtime diagnostics, or diagnostic coverage data necessary for DAL-B certification?
  5. CAN FD and AUTOSAR OS Support:
    • Are there any plans to support CAN FD or AUTOSAR-compliant RTOSes on current or future C2000 devices?

Request:

Could you kindly clarify if there are:

  • Remedies, external safety modules, or roadmap devices from TI that can help bridge the identified gaps?
  • Resources or application notes specifically targeted at implementing DO-178C / DAL-B compliant systems using TMS320F28379D?
  • Recommendations for TI processors with enhanced safety features (e.g., lockstep, CAN FD) that still maintain native Simulink and InstaSPIN integration?

 

Your insights will greatly assist in making an informed decision for our upcoming aerospace and e-mobility development programs.

 

Thank you for your time and support.
