NAND Flash Controller Interface on Zynq US+ PS

Device family overview highlights that Zynq US+ MPSoM feature ONFI 3.1 compliant NAND Flash Controller on Processing System (PS) side. From TRM it is known that it supports SDR and NV-DDR interface types, but what I find not so clear it whether the second is only NV-DDR (ver. 1) or NV-DDR2 as well. While pin naming convention resembles NV-DDR2, some other factors like maximum clock rate (mode 5 with 100 MHz) are similar to NV-DDR.
Should I consider this interface to be NV-DDR2?

Best regards,
Marcin

I believe is NV-DDR. Do you think the pin out is NOT matching NV-DDR?

Re: NAND Flash Controller Interface on Zynq US+ PS

You are right - sorry for long time no visit here, but I must admit that in meantime after sending the question I figured that pin names in Pinout specification are related to SDR interface, not to any NV-DDR.

Anyway, the thing is clear to me and others who possibly are uncertain ;).

 

Best regards,

Marcin
