10M02SCM153C8G POWER USE

Hello,

I have some questions regarding the power supply usage for the MAX10 (10M02SCM153C8G).

Is it absolutely necessary to place a 0.1uF capacitor cloase to each power input pin, or can I create a power plane for the MAX10 and handle it through this power plane?

Since the 10M02SCM153C8G package is small and it's a BGA component, placing a 0.1uF capacitor at each power pin is quite challenging.

Thank you.

Power

    Hi,

    It is recommended that you keep the 0.1uF caps near to the power pins to supply optimal current as required during operation. Hence, suggest you to please follow the Power Distribution Tool recommendation.

      Hi,
      our standard solution is having bypass capacitors at every supply pin at bottom side, preferably connected by VIPPO pins. But actual minimal bypass requirement depends a lot on switching activity and load impedance. We also made single side populated boards with bypass capacitors beside the FPGA package and also functional designs with PQFP packages in the past.

    Hi,

    Recommend you to follow the guidelines provided for the device on following page:

    Notes to the Intel® MAX® 10 FPGA Pin Connection Guidelines

    The above link mainly recommends placement of the capacitors, but eventually user should be doing the board level simulations to check signal integrity of the board.


    As you rightly said, the power consumption depends a lot on the design. For the power consumption estimation use the Early Power Estimator tool:
