Cyclone IV SEU Radiation Level - Cyclone IV SEU Radiation Level We are trying to determine what level of radiation would cause an SEU on the Cyclone IV (EP4CE6E22C8). I was wondering if anyone happened to know, or have some documentation, that would be able to help us determine this level of radiation. Please let me know if there are any questions or concerns. Thanks in advance! Replies: Re: Cyclone IV SEU Radiation Level Hi Nchilli, Sorry for being late, i was checking with internal team about this. Sorry we do not have the information for the radiation level. Thank You Regards, bruce Replies: Re: Cyclone IV SEU Radiation Level Thank you for a quick response! Is there a specific level of radiation that triggers the SEU for the Cyclone IV? I read through the document and did not notice any mention about the radiation level that triggers the SEU. We are looking to do testing inside a radiation chamber and want to know at what level the SEU will be triggered. Please let me know if there are any questions or concerns! Thanks in advance!
