TMS570LS3137-EP: Question about TMS5703137CGWTQEP built-in Flash radiation test

Part Number:TMS570LS3137-EP

Hello,

Does Hi-rel TMS5703137CGWTQEP built-in Flash pass the radiation test?
If built-in Flash is affected by radiation, we want to use EMIF to external Flash, where can download example code to reference.

Thanks,

Andy
