To USB or Not to USB


USB Type-C – Greener every day (and why you don’t need USB Power Delivery)

USB – Greening the Earth with USB Type-C (and actual plants)

USB Type-C standardizes power across devices, across continents, across oceans.

USB Type-C will be the one and only standard for charging phones, tablets, cameras, wearables.  It will be same in cars, homes, offices, and factories.

One connector, one cable.

For phones alone, switching to USB chargers will save on billions of chargers not going into landfills.

The EU chose USB as the standard in 2011.

But the microA/microB wasn’t universal enough. It was cheap but it was different on both ends. It wasn’t particularily durable. And it wasn’t really small enough for even the small Motorola flip phones that were so popular for awhile

Replacing the Micro A and Micro B connectors, Type C fulfills the requirement envisioned by the EU 5 years ago.

With Type-C it’s simple. The symmetry of the connector (flappable) and the cable (either end) makes it easy to use.  It’s durability makes the connector usable for many, many more cycles reliably.  The extra wires/pins/contacts future proof it for faster speeds, more lanes for more protocols.

So, one connector, future proofed, easy to use. Reusable (like good USB IP).  Billions in chargers not going into landfills.

No Power Delivery needed

With power delivery you can even do more power, but you don’t need more power which was the purpose of my previous two entries

USB Type-C: More Power – Part 1

USB Type-C: More Power – Part 2

before Mick’s other two entries, (both useful, though lacking in snail jokes)).

The point of those two entries is this:

What’s great about this for our USB Type C solution, is that you can use our PHYs and controllers “as-is” and do Type C without any additional chips to implement USB Type C for USB 2.0, 3.0, and 3.1.*

You don’t need extra Power Delivery chips.

You just need our PHY and our controller.*

With Type-C you get 15W of power for faster charging. For most devices (phones, tablets, battery chargers, camera chargers) this is all the power you need.

Charging 3.3x faster than USB 3.0 at 4.5W and 7.5x faster than USB 2.0 at 2.5W.

(This is where one of my friends emails me to correct me).

*This is for pure USB 2.0, 3.0, or 3.1. No Alternate Modes like DisplayPort.

*For USB 2.0, you can use a couple of resistors on the PCB. For USB 3.0 and 3.1 in a few cases you might need more.  Those secrets are for those who are, our customers.

Power Delivery, which is getting lots of press, is really only needed for PCs, super tablets, docking stations and monitors.  Stuff with big batteries.  These can take advantage of Power Delivery.

So don’t be fooled, you don’t need Power Delivery, unless you need Power Delivery.

Super Green USB – Bioo Lite

Another way USB is making the world green, is an actual PLANT generating the 5W you can use to charge your phone.
The plant somehow absorbs light and nutrients, creates a charge that can be used to charge a mobile phone a 1A, 5V.  It’s almost too good to be true, since an actual Solar cell probably costs more than the bill of materials for this plant.  Certainly cheaper than the Campfire activated USB charger for your phone.

As close to Wireless Charging as you can get.

Snail Jokes (2)

A snail walks into a bank to make a deposit. Then a turtle comes in and robs the bank.

Afterward, the police are interviewing the snail and asks him to recount what had happened, The snail says, “I don’t know, it all happened so fast!”

What’s the difference between a politician and a snail? One is slimy, a pest and leaves a trail everywhere, and the other is a snail.
