TUSB9261: TUSB9261 design architecture confirm and document request

Vince Wen

Part Number: TUSB9261

Hi,

Since our design plan to use TUSB9261 to transform the SATA interface from USB3.0 interface then to control a M.2 SSD, is it okay of our thought?

If so, would you help to provide the design guideline or reference schematic? Thanks.

Hi Vince,

According to the datasheet the SATA interface on the TUSB9261 conforms to the following specifications:

SATA Interface – Serial ATA Specification Revision 2.6
- Gen1i, Gen1m, Gen2i, and Gen2m
- Support for Mass-Storage Devices Compatible With the ATA/ATAPI-8 Specification

What are the specs for the M.2 SSD?

As for a reference design, you may refer to the product page of the TUSB9261DEMO Evaluation board | TI.com. The schematic is present at the bottom of the TUSB9261 DEMO User's Guide, which is available on the TUSB9261 product page.

Regards,

Nicholaus

Hi Nicholaus,

Our project plan to arrange a M.2 SSD which interface is SATA3.0.

Would you have suggested any other part if TUSB9261 would not support SATA3.0? Thanks.

Hi Vince,

Unfortunately, the TUSB9261 is the only USB-to-SATA bridge we have, and the TUSB9261 doesn't support SATA 3.0 only SATA Gen2. There are no new bridges planned at this time.

Nicholaus
