TDA4VH-Q1: Conflicting Info on USB Count

jeremy borgman

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH,

The datasheet for the TDA4VH is pretty clear that there is just 1 USB port (3.0): https://www.ti.com/lit/ds/symlink/tda4vh-q1.pdf?ts=1697634570994&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTDA4VH-Q1

I also only see one USB port in the BGA pin map for TDA4VH. However in section 8.4.5.31 of the datasheet there are references to USB3SS0 and USB3SS1.

Additionally, the TRM: https://www.ti.com/lit/zip/spruj52 makes reference to USB0 and USB1 in tables 12-193 and 12-194

Can you confirm how many USB2.0 ports the TDA4VH-Q1 can support without an external hub?

Hi Jeremy

There is only one host controller muxed between typc and USB hub ,both can not work simultaneously

usb2.0 controller + serdes is used to support USB3.0.

Seems bug in the TRM we assign thread to the respective owner to confirm on this.

The Device Comparison table in the datasheet is the official list of modules and their # of instances for each part number. Other parts of the datasheet and the TRM may contain device-family "superset" information that may not apply to all part numbers in the device-family.

In the case of USB, however, all devices in the family only support 1 USB port. We will update the datasheet and TRM to reflect that.
