eMMC adapter question to vcc, vccq and 3.3V
 

I have this eMMC adapter from Multi-Com and on this adapter there is for power 1.8V and 2.8V (see picture in attachment) to solder on pcb.

On some eMMC pinouts i see vcc, vccq and also 3.3V (as an example i have put the pinout of the N8000 to the attachment)

My question is:
from adapter pin 1.8V to which pin of vcc, vccq and 3.3V i shall solder?
the same question with adapter pin 2.8V.

or is it:

1.8V = vccq
2.8V = vcc
? = 3.3V

i hope to get an answer as soon as possible,

Hi , there to power lines:

VCC- 2,8...3.3V thats are minimum and maximum values.
VCCQ - 1,8V Power for IO bus.

So thats funny but truth 2.8V = 3.3V

to understand it correctly: as you write 2.8=3.3 this means that my adapter can reach also the maximum value of 3.3V, yes?

furthermore on the emmc pinout of the samsung N8000 which i have uploaded in the first post shows pins for vcc and 3.3V. according to your answer it is

vcc = 3.3V.

so a mistake in the pinout? vcc is supposed to be vccq? or how is this pinout to understand?

The emmc device have tolerance , and u can use 2,8v or 3,3 v , these are the tolerance to power up ur ic .

thanks. would be great when somebody also clears my last question about the pinout of N8000.
