State of USB Spring 2016 – Part 3 (and Snail Jokes)
Dozens of products are now shipping with the USB Type-C connector, making it the fastest adopted USB-IF standard and likely to be in your next USB-enabled SoC. Read on to learn about implementing USB 3.1 and USB Type-C in SoCs and how DesignWare® USB IP can help you get your products to market faster.
USB Type-C makes USB so awesome you can read about how it makes the world a greener place in Scientific American.
The internet is all a buzz this week with news of the Samsung flagship S7 mobile phone. Yes it’s a beautiful phone packed to the brim with super features but sadly NO USB Type-C! instead the Samsung S7 has a Micro USB, old school to say the least.
The big question on people’s minds is if wireless, data transfer and charging, will replace USB in the future. The simple answer is NO, USB is here to stay. For the longer answer read on.
One of the challenges I had ramping back up on USB was understanding all of the advancements in the USB specifications since I last worked as part of the Synopsys DesignWare IP group. Of course along with the advancement of the USB specification also came a slew of new acronyms. Anything confusion I encountered was the connection between USB Type-C and USB 3.1. Apparently the confusion between USB Type-C and USB 3.1 is common as a simple search resulted in many technical article links, including the one below which I thought was a very good summary explanation.
I ran into this article online last week, http://www.laptopmag.com/articles/how-to-find-safe-usb-type-c-cables it discusses how a bad USB Type-C cable fried a Google engineers equipment, including a Chromebook Pixel. It also covers another issue when another bad Type-C cable drew too much power from a laptops port killing them. I highly suggest you read the article, but if you don’t have time then in summary; when a low quality, uncertified USB Type-C cable was used the incorrect resistance value for Type-C configuration causes the device to think it’s connected to a 3amp USB Type-C connection. Drawing 3A from a 500mA or 900mA port is not a good idea; the extra current draw damaged both devices. This issues reared its ugly head when using a USB Type-C to USB Type-A uncertified cable.
Morten Christiansen authored today’s blog on the industry’s first plugfest earlier this month. At this exciting event, USB Engineers (no marketing people generally) bring their products on carts, and go from hotel room to hotel room interoperating their products with stationary products. Morten as spent a lot of time writing and contributing to standards at Ericsson for mobile phones. He’s our Technical Marketing Manager for USB products, a great guy and a fantastic engineer, and a true expert on USB applications. Hopefully he will write for us more in the future.
