    MTBF for Intel CPUs

    johnluo Community Member



      Would anybody help me to find the MTBF or FIT reliability information for the following Intel parts?


      FH8065301487717 SR1X6 CPU
      LH8066803102601 SR33P CPU
      10M02SCU169I7G FPGA


      Thank you very much!

          Hello, johnluo:


          Thank you for contacting Intel Embedded Community.


          The FH8065301487717 SR1X6 [Intel(R) Atom(TM) Processor E3845 D0 Stepping] Failures in Time (FIT) information is stated on page 3 of the Production Release Qualification (PRQ) Report Intel(R) Atom(TM) Processor E3800 Product Family D0 Stepping.


          The information of the rest of the listed devices can be found in their PRQ reports that should be requested by filling out the Submit a QDMS Support Request form.


          It is important to let you know that the FIT is a standard industry value defined as the Failure Rate (λ) per billion hours. It can be expressed as:


          FIT = λFIT = λhours ×109


          By the way, the Mean Time Between Failure (MTBF) is another standard industry value which predicted elapsed time between inherent failures of a system, during normal system operation. It can be calculated using the following formula:


          MTBF = 1 / FIT


          We hope that this information may help you.


          Best regards,
