Does I.MX6Q Have Configurable Generic Processor Bus (Interface) / Enhance Host Controller Interface?

brightwang — Thu, 01 Sep 2016 04:22:47 GMT

As Title My Question Is For That I Need An USB Host Controller Like SAF1760BE With My Selected Application Processor I.MX6Q But Find No Such An Interface In Documents.

SAF1760BE

Hi-Speed Universal Serial Bus host controller for embedded applications

But Unfortunately I Can't Find What Is The Interface Between This USB Host Controller And I.MX6Q. The Only Way To Expand The USB Port Seems HSIC USB Host Controller. As You Know There Are Only Few USB Host Controllers With HSIC Interfaces. In Fact Only Microchip Has That Kind Of Parts.

The i.MX6Quad processor has the integrated USB Host core with one downstream port with PHY. You can easily expand the number of downstream ports by adding an external USB Hub IC, such as the following ones from Microchip:

or Texas Instruments:

or Cypress:

Please note that NXP cannot recommend one vendor/product over another in any way.

Have a great day,

Hello Artur

Thank You For Your Reply But My Question Is Can It Be Possible To Use SAF1760BE With I.MX6Q?

As You See Here Is An HSIC Bus Bridge With OTG / HOST And Only Microchip Has HSIC Base USB Host Controllers And I Need Them All Are AEC-Q100 Qualified Parts And Won't Use USB Host Port Of I.MX6Q To Expand USB Ports

Seems that it is possible to use the EIM bus of the i.MX6Q processor to connect the SAF1760BE chip to it. For more details, please refer to the Chapter 22 of the i.MX6Dual/Quad Reference Manual document.

Best Regards,

Artur
