Seeking Feedback about Roadtesting a USB Type-C Interface Detection Eval Board?

rscasny
rscasny over 2 years ago

imageMore of our suppliers are rolling out USB products.  USB is an evolving standard and given its popularity in the market place, I'm not surprised with the interest by our suppliers.

I am planning on roadtesting a USB Type-C interface detection board.

I wanted to tell you about it. If you have time, please vote in the poll below. Thanks.

Some info about the eval board:

The FUSB302 evaluation board (EVB) and included software allows customers a complete platform to evaluate the Type-C interface detection solution the FUSB302 provides. The EVB is designed for both stand-alone operation and connection to test equipment for specific testing requirements. The FUSB302 software provides both fully automatic control and manual control of the FUSB302 functions. With a single connection to a PC and a couple configurations in the GUI, the EVB can function as a source, sink or dual-role port.

The FUSB302 targets system designers looking to implement a DRP/DFP/UFP USB Type-C connector with low amount of programmability. The FUSB302 does the USB Type-C detection including attach, and orientation. The FUSB302 integrates the physical layer of the USB BMC Power Delivery (PD) protocol to allow up to 100 W of power and role swap. The BMC PD block enables full support for alternative interfaces of the Type-C specification.

Here are some documentation:

  • Datasheet: 
  • FUSB302B: 
  • User Manual: 
  • Overview: 
  • Test Procedure: 
  • Videos: 

The sponsor does provide a test procedure. I think that could be the focus of a roadtest. However, you can design your own tests. The sponsor is flexible.

Beyond the eval board, what else would you need for the roadtest? Please tell me in the comments.

I think this could be a roadtest for both an experienced and a less-experienced roadtester. It definitely will teach you more about USB Type C.

If you have the time, I'd appreciate you voting:

    USB C power negotiation is definitely of interest. I am starting to build test capability for USB C power sources because I don't think it is avoidable. This road test would be good to help get up the learning curve around USB C.

    I would need a pair of boards, both for source and sink. 
    Slightly unrelated: Fairchild was acquired in 2016. Why the name on the silkscreen?

    The user manual was written 2015, The On Semi branded one linked in above is updated 2018, and shows Fairchild on the PCB photo too. This reference design seems to have happened in parallel with the acquisition.

    The PCB has a 2016 datestamp in the silkscreen

    maybe manufacturer has provided outdated photo, current ones seem to have a "ON" logo at the center:

    interesting module - it seems that it also has PIC32 MCU for communication with dedicated PC software/GUI, so more vectors to test...
