TUSB7320: Some questions

Part Number: TUSB7320
Other Parts Discussed in Thread: TUSB7340

Hi Sirs,

Sorry to bother you.

We have requirement for PCIEx1 (GEN2) to USB3.0, USB3.0 speed needs to meet 350MB/s. 

So we found TUSB7320.

We would like to know 

1. Two USB ports work at the same time, at TA of 50 degrees C, what is the fastest speed of each port?
2. Is there a FW inside? Need to update or burn?

    Hello Shu-Cheng,

    Please be aware that TUSB7340 / TUSB7320 are NRND (Not Recommended for New Designs) devices and support is limited to existing documentation only.

    Both downstream ports can operate at SuperSpeed (5G) simultaneously.  Real world throughput will depend upon protocol overhead and PCIe bandwidth.

    There is no external firmware component to this device.

    Regards,
