Universal Serial Bus 3.0

INFINITE POSSIBILITIES!

Page 2: USB 3.0

What is USB?

Page 3: USB 3.0

What is USB?

USB stands for Universal Serial BusProvides an expandable, fast, bi-

directional, low cost, hot pluggable Plug and Play serial hardware interface

Allows users to connect a wide variety of peripherals to a computer and have them automatically configured and ready to use

Page 4: USB 3.0

What is USB? contd.

Implemented to provide a replacement for legacy ports to make the addition of peripheral devices quick and easy for the end user

History of USB

Page 6: USB 3.0

History of USB

Developed and standardized by a group of leading companies from the computer and electronics industries in 1995

USB specifications were developed by Compaq, DEC, IBM, Intel , Microsoft, and NEC, joined later by HP, Lucent, and Phillips

Page 7: USB 3.0

History of USB contd.

These companies formed the USB Implementers Forum as a non-profit to publish specifications and provide a support organization and forum for the advancement and adoption of USB technology

There have been three versions released prior to 3.0

Page 8: USB 3.0

History of USB contd.

USB 1.0 in January 1996 – data rates of 1.5 Mbps and 12 Mbps

USB 1.1 in September 1998 – first widely used version of USB

USB 2.0 in April 2000Major feature revision was the addition of a high

speed transfer rate of 480 Mbps Important note – all versions are backwards

compatible with previous versions of USB

USB Now

The next generation of USB hardware and specifications is USB 3.0

Version was announced by Pat Gelsinger at the Intel Developer Forum in September 2007

USB 3.0 Promoter Group announced in November 2008

Why the upgrade?

Page 12: USB 3.0

Why the upgrade?

Mainly the need for faster transfer rates in devices such as hard drives, flash card readers, and DVD, Blu-ray, and HD DVD optical drives

User applications demanding a higher performance connection between the PC and peripherals

Page 13: USB 3.0

Why the upgrade? contd.

Need for greater energy efficiency in today’s “greener world”

USB 3.0 Connector

Page 29: USB 3.0

USB 3.0 Standard-A connector

Std A – Same interface as USB 2.0 Standard-A connector, but with added pins for USB 3.0 Super-Speed signals

Complete campatibility with USB 2.0 Standard-A connector

Page 30: USB 3.0

USB 3.0 Standard-A connector contd.

Double-stacked connectors supported

Page 31: USB 3.0

USB 3.0 Standard-B connector

Std B – Defined for relativley large, stationary peripherals such as hard drivers and printers

Visually different from USB 2.0 Standard-B connectorBut the receptacle accepts a USB 2.0

Standard-B plug

Page 32: USB 3.0

USB 3.0 Standard-B connector contd.

Developed for device-powered applicationsFor example – wireless adaptors

Page 33: USB 3.0

USB 3.0 Standard-B connector contd.

Based on the USB 3.0 Standard-B connector design, but with additional device POWER and GND pins for a device to supply power

The receptacle accepts the USB 3.0 Powered-B plug, USB 3.0 Standard-B plug,or USB 2.0 Standard-B plug
