Hi Tetsuo,

Could you please explain what you mean by the depth of endpoint? If you mean size, then:

The maximum packet size for Superspeed is 1024 bytes and the maximum burst length is 16, so the maximum endpoint size for a bulk endpoint is 16KB.

Best Regards,
AliAsgar

AliAsgar-san,

Thank you for your comment.

As you say, "depth" is the size of the EP.
FX2LP has the following figure in the data sheet.

Is the same information in FX3?

No, the endpoint configuration information is not present for FX3.

AliAsgar-san,

Thank you for your support again.

Is the maximum EP size different from FS and SS?
I am thinking of using CYUSB2014 because it is USB2.0.

Thanks,
Tetsuo

Hi Tetsuo-san,

Yes, maximum endpoint size is different for FS and SS. Maximum packet size for a FS is 64 bytes and does not support burst transfer, Maximum packet size for a SS is 1024 bytes and supports burst transfers upto burst length 16.
