Our customer make the K70 board refer schematics of the TWR-K70F120M.

They believe that the following bypass capacitors of the K70's DDR_VDD and DDR2 Memory's VDD, VDDQ are listed in page 10 of the TWR-K70F120M schematics. And these bypass capacitors located between K70 and DDR2 memory.

- 0.1uF x 16pcs

- 47uF x 1pc.

Are they correct?

Should they add more bypass capacitors?


Please advise as soon as possible.
