Dears,
My customer used TI DSP TMS320F28032PNT for a power delivery project.
For TMS320F28032PNT,these are two Device Markings:C A and G4A,These are two Wafer Fab Code.
if customer usesd C A marking device, CAN Interface commnication is OK.
The same PCBA,If customer used G4A marking device ,CAN Interface commnication is OK in normal temperature,but CAN communication failure in Temperature above 50 degrees.
what the difference these two Wafer Fab,please advise,
How to fix CAN communication failure issue,thanks!
