Vybrid LPDDR2 Hardware interface

Dear Experts,

We are planning to use LPDDR2 memory (Winbond's W97AH6KBVX) with Vybrid VF5xx MPU.

Unfortunately the hardware interface / DDR Connection information given in Figure 18, Pg. 34 of Hardware development guide (VYBRIDHDUG, Rev. 1, 05/2015) is very confusing. Moreover, the pin naming for Vybrid, by default, is given for DDR3 memory.

Since we couldn't find any interface example in any documents, we were wondering whether we overlooked any or not.

Please help in providing the proper hardware interface for LPDDR2.

Hoping for your kind support.

Thank you,

Warm regards,

Suchith

Hi karinavalencia,

I lack of experience with DDR but I belive that Suchith can use Processor Expert calibration tool as startup.
