Dear all,

We want to evaluate the AC timing of the SD card.
Would you tell me the terminal load capacity about each pin?
(tolerance and dispersion(Variation) by the temperature)

I referred to a data sheet, but was not able to find it.

Best Regards,
Yuuki

Hello,

You may use device IBIS model to get such pins parameter as capacity.

i.MX6S|i.MX 6Solo Processors|Multimedia|NXP 

C_pkg typ = 7.39741pF
C_pin of SD1_DATA0  is 1.29006pF

  Let me remind, if R_pin, L_pin, and C_pin parameters (FOR THAT PIN ONLY) are
not declared, this means the default package values (R_pkg, L_pkg, C_pkg,
specified under [Package]) should be used.
And, if individual pin parasitic value of R_pin, L_pin and C_pin are available,
the values R_pkg, L_pkg and C_pkg are ignored. 

Have a great day,
Yuri
