    CY25422FSXI and CY25422FSXIT devices

      Hello,

       

      We received some CY25422FSXI devices that according to the datasheet are field programmable BUT the devices we received are saying they have already been programmed. We received these devices from Cypress through our customer.

       

      The datasheet(Page 12): http://www.cypress.com/file/137771/download

       

      On page 12 of the datasheet there is a footnote 6 for the field programmable devices which states "The devices mentioned in this datasheet are available as factory-programmable parts and not as field-programmable parts, since the associated programming software is currently not available. Visit www.cypress.com to create a Technical Support case, so Cypress can provide a programming file (.jed file) that matches your requirements."

       

      Is this saying that if we get a CY25422FSXI and CY25422FSXIT device that it is factory programmed and NOT field programmable device? The note is confusing but it might explain why I am getting the device is already programmed message. Please clarify.

       

      The devices I have show this for the marking on the device itself:

      CY25442

      FSXI

      7311036

       

      Thanks in advance for your assistance.

          Hi

           

          1) Can you let us know how you are checking if the parts are programmed or not. Are you powering up the device and checking the output ?

          2) Do you have the CY3675 kit and programming adapter to program the blank devices ?

          3 ) Do you have the JEDEC file with you as per your requirements to program onto the blank devices ?

           

          Thanks,

          Pradipta.

            Pradipta,

             

            Thanks for your email.

             

             

            1)      Can you let us know how you are checking if the parts are programmed or not. Are you powering up the device and checking the output ?

             

            ANSWER: The BPM Microsystems programmer that supports this device tells us this when we try and program the device.

             

             

             

            2)      Do you have the CY3675 kit and programming adapter to program the blank devices ?

             

            ANSWER: We are using a BPM Microsystems programmer and their socket to program these devices.

             

             

            3 ) Do you have the JEDEC file with you as per your requirements to program onto the blank devices ?

                                    ANSWER: We are using the JEDEC file that our customer provided to program this devices with.

             

            Best regards,
