TMS320F28379D: dsp

Bo-Jie Wang

I have a DSP TMS320F28379D mounted on an expansion board, and I applied 15 volts to one of its pins. As a result, I can no longer program the DSP. Could you please advise on how to resolve this issue?

Unfortunately I believe you have permanently damaged the device and it will need to be replaced. Please see the Absolute Maximum Ratings section of the datasheet.

So I can't replace internal components like resistors, capacitors, IC. to repair the DSP?

If you applied 15V to the DSP it is almost certainly damaged. There is no way to repair the DSP. You might be able to replace the DSP on the board if you have the correct skills and equipment.

If you meant that you applied 15V to your board, it might be possible that the DSP is undamaged and replacing components on the PCB could resolve the issue, however we will not be able to support this debug.

Sorry, but is it possible to find the complete circuit diagram or schematic for the F2837x controlCARD R1.3 online? I want to see which components might have been damaged when I applied 15V to it.
