Max V SEU mitigation

Dear Sirs,

I plan to use MAX V CPLD for an application exposed to ionizing radiation.

Do you have any papers about MAX V SEU testing and results, for both CRAM (configuration RAM) and CFM (configuration flash memory)?

Does the device implement SEU mitigation like CRC or someting else? I will not use TMR (triple modular redundancy) technique.

Best regards,

Randrian

    Hi Randrian,


    Here's currently no documentation for MAX V SEU mitigation. Also, CRC is not used in MAX V.

    If you would like to know the FIT rate for MAX V device, you can log in Resource & Documentation Center (intel.com) with NDA and search for "Reliability Monitoring" report.

    Also, there is an "SEU FIT Report" in Quartus, which is license-required .


    Thanks & Regards,

    Xiaoyan

    Hi Xiaoyan,

    For my design, I will replace a MAX II-based old design by MAX V. Could you please confirm if the FIT rate of MAX V device is the same as the FIT of MAX II?

    Best regards,

    Alexandre

    Hi Randrian,

    Yes. MAX V and MAX II used the same process technology, so the FIT rates are the same.

    Hi Xiaoyan,

    What about the flash data retention, how many years for 12hours use per day?

    Hi Alexandre,


    Sorry I could not find this data you mentioned.

    There's only "Erase and reprogram cycles" listed in MAX V Datasheet and the reliability monitoring report.


    Thanks & Regards,

    Xiaoyan

      Hi Xiaoyan,

      Could you tell me if the data retention should be the same as Max II?

      Best regards,

    Hi Alexandre.

    I just further checked documentations.

    The estimated Data Retention hours for MAX II and MAX V are the same, because they used the same FLASH memory process technology.

    Thanks & Regards,
