TOP MARKING of XC5VLX30-1FFG676C

We ship the XC5VLX30-1FFG676C to user, but user said the marking is not the same as they bought before.(User didn't tell us where they bought from before.)

User said top marking should be in the middle of the IC, but our part's marking is on the left side of ICs.

Could you tell us the marking as attechment is correct or not ?

The part marking on the device in your image looks correct and the up to date V5 marking. The customer probably has the older V5 parts with ink marking. Checkout the notice XCN13015 linked by other above showing the transition to laser marking. The only thing that seems off to me is at the bottom. If your customer still needs assurance you can try providing a PO copy to them to verify it was obtained via Xilinx authorized channel.

Hello freda@saint-nation.com 

I checked internally, this part is not authentic (shown in image).

Please check this part purchased from Xilinx autorized channel or not.

a)

only purchase from an authorised distributor,
if you purchase on the grey market, how do you knwo whats under the lid ?
would yo be happy as customer purchasing a board from an grey supplier ?


I've seen customers that purchase parts that are just plastic, no silicon,
others that have purchase -3 industrial only ti find out later when they get lots of returns, they are really -1 commercial parts,

Engineering sample parts re banged as full spec. industrial parts are also around

I understand form a good source, that at one of the Xilinx sites, they have a wall of counterfeit parts.

As our far eastern friends make the equipment used to mark up chips, its no surprise that counterfeit is so easy and so profitable.

That second image is of a valid lot. However as many of us have stated already on this thread you can verify the parts as authentic by sourcing the devices from Xilinx authorized distributors... This can be verified via a purchase order or PO. If your customer needs assurance of authentication send them a copy of the PO that was received when the lot was purchased/received from a Xilinx authorized distributor.
