TMS320F28027: Noise immunity in RAM execution

Part Number: TMS320F28027


Hello.
Please tell me about the code execution in RAM of TMS320F series.

At initialization time, the critical code (control operation) uses the memcpy() function,
It is running on RAM.

However, is there any problem in executing code in RAM in a noisy environment such as in-vehicle use?
Was pointed out.
I am concerned about garbled data in RAM.
Is there a difference in noise immunity between FLASH execution and RAM execution?

Please let us know what you think.
Best regards,

.

    Hi,

    No, their is no problem in executing from RAM Vs Flash as long as supplies dont fall below minimum spec range. In that case you will loose content from RAM, and will have to re load the code and re-execute from RAM (since RAM is volatile memory).

    Also, their is BOR circuit on the device which will reset the device, if the supply voltage glitches beyond certain level. Please refer data manual for Recommended Operating Conditions.

    Regards,

    Thank you for your reply.
    I was relieved that there was no problem unless the device was reset.
    Is there any technical data that explains the fact that there is no difference in noise immunity between flash and RAM?
    Please introduce if any.
    I would like to use it as an explanatory material for this matter.
    Best regards,
