To Technical Support:

I was wondering if you could provide die verification for one of your products, S25FL128SAGNFI011. Upon exposing the die, the markings revealed 98740A. My question is are these markings correct for this device?

Our company does component authentication for a government prime contractor who requires to have the die markings match the external markings exactly or receive verification from the manufacturer.

I have included pictures of the component going through authentication testing and a picture of the die markings revealed post decapsulation.

Thank you in advance for any assistance that you are able to provide.

Kind Regards

Hello Mitch,

Thank you for contacting Infineon Technologies.

The internal die marking (IDV = 98740A) does, in fact, match that of the S25FL128S.

Please find attached the S25FL128S Qual Summary, and refer to "Die :  98740A
