TUSB9261: TUSB9261

Part Number: TUSB9261

Hi,

I have please some questions regarding the TUSB9261, USB to SATA converter :

1. How do I program the TUSB9261 external flash device ?

2. Where can I found the TUSB9261 flash updated firmware ?

3. Does it needed to give the device reset signal ?

4. If I use an external oscillator, Does the chip VSS Oscillator is the actual GND for the Oscillator, or other direct GND connection is required ?

Thanks a lot,

Gil

  • Hi Gil,

    1/2 See the software section here: www.ti.com/.../toolssoftware
    3. Yes, see section 7.3.1.4 in the TUSB9261 datasheet.
    4. See section 7.3.2.1 in the TUSB9261 datasheet.

  • Hi JMMN,

    Your answer helped me a lot, And I already implemented the issues in my design.
    I have another question, that raised during the design...
    The TUSB9261 eval board used SPI serial flash : PMC- Pm25LV512A.
    Assuming that we already used another vendor serial SPI flash in our company : ST- M95512-W ,
    My question is :
    Can we use any type of 512 Kbit serial flash with the TUSB9261, or there is importance to use only the Pm25LV512A device?
    Thanks again,
    Gil
  • Hi Gil,

    There are some SPI flash requirements in the datasheet, section 8.2.2.4, but a variety of SPI devices can be used with the TUSB9261 device.
