We use MAX V part number 5M570ZM100I5N and the parts appear to be dual marked with both the "C4" and "I5" temperature range and speed grade.

Can you confirm that this part number is supplied by Intel dual marked? We have been purchasing this part number from Digi-Key. I've attached a photo showing the part marking.

Hi SAhlq,

Thank you for contacting Intel Community.

Please note that dual part markings on MAX® V devices are intended to show -4 commercial specifications also meet the -5 industrial specifications.

Refer to our KDB: https://www.intel.com/content/altera-www/global/en_us/index/support/support-resources/knowledge-base/solutions/rd04122012_986.html

Intel PSG has its authorized distributor to sale Intel devices. If you got the devices from formal distributors, you shouldn’t worry on the device authenticity as the devices must be valid units. Otherwise, we do not ensure the device quality and do not provide the further service. You may find the authorized distributor list from the link below:

Hope this clarify the queries.

Regards,

Aiman

Hello Aiman, I did stumble across that same community/forum post concerning the MAX V dual marking late yesterday. It just seems strange that this type of notification wouldn’t be contained in a Product Change Notification like most other manufacturers use. Also, the 2nd link in your response does not bring me to a list of Intel authorized distributors, but instead brings me to Intel’s BUY ONLINE area where it looks like you can purchase directly from your company. Thank you for your quick response on this issue. Scott A.
