Simplest, Smartest and Lowest Cost USB Type-C

We have been seeing a lot of interest in all things USB Type-C from basic USB 2.0 Type-C support all the way to the higher end USB Type-C Alt Mode with DisplayPort. Actually, the latter is getting the most focus as it’s far more complex than traditional standalone USB operation and it’s a highly desirable use mode. Many of the questions are asking for our recommendation as to how to handle the high power, high voltage power delivery and Type-C Port Controller hardware. This is a complex HW partitioning, SW partitioning and system architecture question.

Simplifying USB Software Development

Software developers constantly face the challenge of integrating more features into their designs, with fewer resources and shorter schedule for fast time-to-market products requiring USB interfaces. Developers programming in Linux have an additional challenge in that the Linux kernel mainline is officially released as a new version approximately every 2 to 3 months. Keeping up with the version changes and using them for a non-mainline kernel can waste weeks or months of development.

USB is easy because USB is hard (made by hard working engineers)

Back in the 20th century, my first meeting meeting as USB PMM was with Mr. Ed Beeman in December 1999.   In May, 2000, We demonstrated our USB 2.0 Device controller IP in an HP ScanJet scanner.  One of the very first demonstrations in an actual product.

Relationships Between USB Specs, Part Two & Where to Learn more about Type-C and DisplayPort alt mode

Recently I blogged on the relationships between USB Type-C, USB 3.1, Power Delivery and DisplayPort specifications. In my last blog I simplified the view focusing on the important and latest specifications. I think the simplified view answer most designer’s questions but there are still a few that like to see the full history and complex interactions. The below image, click to enlarge, provides a more detailed view of the different specifications, timeline representation and relationships.
