15.3 Errata Summary mention Silicon reversion has Rev.B & Rev.C.
Which silicon reversion is Cypress current ship out?
How to identify?
I think both rev are shipping out, though not sure. There is method to identify the rev, mostly from lot code. You will need to contact your local Cypress sales team.
P.S. I notice your colleague is asking the similar questions to quality team. You could get response in this week.
