TUSB7340: Reason for making it NRND

Part Number: TUSB7340

Hi,

I would like to know why the USB HOST controller products were all NRND.

I believe TI is focusing on USB products.

Best Regards,

Kenji

    Hi Brian,

    I feel sympathy for not having a host controller team, but I would like to know the reason.
    I’m waiting for your reply for a long time.

    Best Regards,
    Kenji

    Hi Kenji,

    TI is continuing to focus on USB products (redrivers, hubs, switches, etc), but we are no longer focusing on the host controller portion of the market. The existing TI host controller portfolio was moved to NRND for several reasons. One is that the devices were designed almost 10 years ago to specifications that have evolved considerably since that time. See section 11.2.1.1 in the TUSB7340 datasheet, the USB 3.0 spec is now on version USB 3.2 and the xHCI specification is now on version 1.1. The second is that we can no longer provide the on-going software / driver support to help customers implement our older xHCI design into every new generation of operating system.
