The operating current range about the GPIO of IMX6S

[王剑翰]

I can not find the information about the operating current range about the GPIO of IMX6S. Could you help to show the information?

Hi 王 剑翰

max. GPIO current is not specified however it can be

calculated using sect.4.6.2 General Purpose I/O (GPIO) DC Parameters,

4.8.1 GPIO Output Buffer Impedance IMX6DQCEC or

using ibis model IMX6_DQ_IBIS : i.MX 6Quad and i.MX 6Dual IBIS File.

Hi Igor,

Thank you for your kindly reply.

I am sorry for it. I check the sect.4.6.2 General Purpose I/O (GPIO) DC Parameters and find there is the max. current restriction for GPIO.

I think your meaning is there is not the specified range for the GPIO output current. The parameters in this table is only for the GPIO input current.

Please let me know whether my understanding is correct, thank you!

Hi 王 剑翰

yes, my answer was for GPIO output current.
