hercules microcontroller in avionics

romain le guen
Prodigy 30 points

hello,

 

i' m trying to check the possibility to use Hecules microcontroller in avionic systems.

I have an other application with DAVINCI processors.

 

My concern is about avionic certification for DAL C level of safety.

 

Since ARM core is an IP inside the HERCULES Microcontroller, i need to provide certification proof related to this IP

such as 

    developpement process,

    life cycle data,

    functionnal robustness verification performed at isolated IP level,

    unused functions ( if any ) and what ensures they are disabled.

 

Do you provide these informations with the certification package ? Was it a concern for you for SIL3 certification ?

Do you have feedback from your customer about avionics certification of ARM based microcontroler ?

Do you have  "in service experience" information about ARM based microcontroler used in a safety safety critical applications.

 

thank you,

romain

    Hello Romain,

    I fear I am not well familiar with the DAL C requirements but will do my best to assist.

    As of today we have detail documentation on the ARM Cortex R4F core validation process but cannot make this publicly available.  Such documentation has been used in the past to support TI's safety assessments as well as safety assessments for customer systems.  We can work with you to set up contacts at ARM to obtain this information under NDA.  Providing such info is quite challenging as the documents disclose highly sensitive competitive info from an IP developer's perspective.  I realize this is less than optimal from your perspective and we are working on a cleaner solution which can be managed without NDA in the near future.

    As of today there are multiple developers who are evaluating and developing avionics with the Hercules family.  I am not aware whether any of our avionics customers have yet completed a full product and gone through an assessment/certification.

    TI has been using the ARM7 (TMS470R1x, TMS470P) in high volume automotive safety applications since the 1990s.  The first TMS470M Cortex M3 and TMS570 Cortex R4 based products were designed in the mid 2000s for safety applications, with TI introducing many safety features directly into the CPU development with ARM.  Presently ARM based MCU solutions from TI are shipping in high volume for braking, airbag, and RADAR safety applications for over a decade.  This is presently expanding into steering, electric/hybrid electric powertrain, driver assistance, and traditional powertrain applications due to need for enhanced safety.

    Hi,

    I came across this thread searching for DO-254 compliance issues and I'd like to ask if there are some updates since the last answer has been added regarding TI µC devices for use in aerospace applications. Besides the DAL C requested in the original thread, I also like to extend the question on DAL A and DAL B devices. According DO-254 I would assume the safeTI processors - cerified for ISO 26262 and SIL re. IEC 61508 - would be highly complex devices, ths the required documentation of internal structure, maturity, production process stability, product service experience in safety critical applications,.. would make it impossible to cerity this unit by the end user. Did TI already investigated aerospace application related certification aspects?

    Kind regards, Carlhermann

    Hello,

    At this time we do not have a specific compliance package for DO-254, regardless of target DAL.  We have delivered existing IEC 61508 documentation to a number of aerospace customers to date but have not received much feedback.  If you are interested to register for the detailed documentation (safety analysis reports, available assessment reports, etc.) then you can request access by filling out the forms at http://www.ti.com/safetyreport.
