How to connect the unused pins on 6748?

Traian Mitrache

I do not intend to use the USB, SATA, PHY ports in my 6748. What should I do with the POWER PINS, and with th eother IOs?

Is there a comprehensive document that describes how is one to connect the unused pins (power and IOs)?

Hi Traian

We expect to have this information published in the c6748 datasheet in an upcoming revision of the datasheet. Till then you can use the tables in the attached document as a reference.

Let us know if you have any additional questions or concerns on this.

Additionally we have schematic review checklist with a section on what to do with the unused pins, which contains the same information Mukul attached to his post: http://processors.wiki.ti.com/index.php/OMAP-L1x_Schematic_Review_Checklist#If_not_used

Hello

Our device have USB0, USB1 and SATA but we don't want to use their (we don't want mounting elements on PCB). Below there are lists of pins configuration.
Can USB0_VDDA33, USB0_VDDA18, USB1_VDDA33, USB1_VDDA18 and SATA_VDDR still be supplied when other pins are like below.
