USB 3.1 Specification

• Performance

• SuperSpeed USB 10 Gbps

• Delivers a 2x improvement over USB 3.0 5 Gbps data rate

• Power

• USB Power Delivery v2.0

• USB Power Delivery can deliver up to 100W

• Cable and Connector

• New USB Type-C

• New cable and connector scheme enables thinner and

sleeker product designs

(9)

USB Power Delivery 2.0 – Key

Characteristics

• Compatible with existing USB 2.0 and USB 3.1 cables and connectors

• Power

• Enables voltage, current and direction to be negotiated

• Enables higher voltage and current in order to deliver power up to 100W

• Limits to match cable capabilities

• Upper limit bound by international safety requirements

• Switchable source of power delivery without changing cable direction

• Coexists with USB Battery Charging 1.2

• USB Type-C extensions beyond power  new with USB PD 2.0

• Swapping of host and device roles

• Communication with USB Type-C Electronically Marked Cables

• Discovery and configuring USB Type-C Alternate Modes

(10)

• Existing USB Standard-A host connector is too large

for emerging computing platform needs

• Ultra-thin, convertible, detachable and tablet form factors are in need of thinner connector solutions

• Existing USB 3.0 Micro-AB doesn’t meet robustness and

usability requirements beyond phone usages

• Existing USB connector types are difficult to use

• User confusion over plug orientation, cable direction

• The new USB Type-C Cables and Connectors address these issues –

extending and advancing USB as the peripheral connection of choice.

(14)

USB Type-C Alternate Mode

• Specification defines functional extensions that enable USB Type-C hosts

and devices to support optional capabilities

• Alternate Mode

• Permits a vendor or standards organization to utilize the USB Type-C

cable and connector and provide additional features

• Vendors or standards organizations will be required to obtain a standard

or vendor ID (SVID) assigned by the USB-IF

• The USB-IF is also in the process of defining joint identification

guidelines to ensure consumers can easily recognize what capabilities a

USB Type-C capable host or device supports

(15)

Summary

• USB is delivering a single-cable solution for all devices

• SuperSpeed USB 10 Gbps, USB PD and USB Type-C

• SuperSpeed USB 10 Gbps delivers compelling performance boosts to meet

requirements for USB storage, display and docking applications

• New and improved USB Power Delivery v2.0 specification

• USB Type-C cable and connector will bring USB to new and exciting

form-factor platforms

• This next generation of USB technology opens the door for the invention of an

entirely new, super thin class of devices that consumers haven’t even seen yet
