Hi all,
Today I have bought 2pcs CY8C4248AZI-L485, when I received it, I confirm the mark number is right on the chip, and then I solder it on my PCB, and use the MiniProg3 to try to download my program, in the PSOC creator, I found the software defect the chip part number is CY8C4246AZI-L433. and then I go to solder the second chip, it is same, PSOC creator defect the chip part number is still CY8C4246AZI-L433.
Why it is? TKS!

Welcome in the forum.
The devices are different. I would suggest to get in contact with Cypress directly: At top of this page: Design Support -> Create a Support Case. There is seemingly something darn wrong.

Nonetheless I would contact Cypress!!! The marking of the chips is not done outside the Cypress fab, so there might be a source of fake chips. Imho it is rather unlikely to have chips marked wrongly.

Yes, I may agree with your fake chips comments, I have only gone to try, and I have rejected it. TKS.
