Hi Pbins,

Thank you for contacting Intel Community. Would you share with me how the difference chip look like between this 2 parts?

For your information, Intel FPGA is introducing "Green" Bill of Materials for the Cyclone II device families in year 2012. There is a slight increase to the mold compound coverage for F672 packages devices. For details, kindly refer to PCN1105:

Thank you

​Hello Chia. I've attached a file <Different Looking EP2C35F672C8Ns 190619.pdf> that shows the visible differences between the two I have on-hand. One of our board manufacturers told us the "Larger" one looks counterfeit! Does the "Larger" FPGA appear to be genuine?
