Hello

on 3256 datasheet in recommended operating condition section we have:

a) Supply Core voltage DVDD 1.08 1.2 1.32 V

b) Supply 1.2V analog voltage VDDA_PLL 1.08 1.2 1.32 V

c) Supply I/O voltage OVDD 3.0 3.3 3.6 V
 
My question is:

How many current need any voltage?
Thanks

Nobody really knows, but:

If you want only a slight overclock, or no overclock at all, Core current should be about 2A per chip. If you want to overclock them hard, make that 3 or more.
In the K16, the VDDA supply was about 75mA per chip (600mA LDO for 8 chips), and it was working OK. For the I/O, count the same (75mA/chip).
