About power supply pin SDRAMC_VDD2P5

[keisukewatanabe]

Dear support,

About power supply pin SDRAMC_VDD2P5, I recognize it to be power supply input for DDR1, is it right?

When they use DDR3, will the disposal of this power supply pins be necessary?

(I consider whether cost and implementation area down are possible.)

Best regards,

Keisuke

Hi Keisuke,

  Those pins should be connected to DECAP_V25_LDO_OUT, as seen on the tower board. They are required for DDR3 operation.
