Hello
I hope you are well.
I'm not able to confirm if this device is suitable for DoIP since I do not know the specific requirements for that application.
RT1170 features make possible the use of Ethernet, FlexCAN. It is possible to add external memories but I cannot assure you that these features can fulfill your specific application.
Unfortunately, we do not have any example of this but if you provide more detail about the specific requirements of your application we could have better criteria to check if this device is suitable.
Best regards,
Omar
