2. INTRODUCTION
• The USB 3.0 Promoter Group announced on
November 17, 2008, version 3.0 and
submitted to USB-IF
• The first certified USB 3.0 consumer products
were announced January 5, 2010

3. UNIVERSAL SERIAL BUS
• Designed to allow many peripherals to be
connected using a single standardized
interface socket.
• Consists of a host, USB ports, and peripheral
devices connected in a tiered-star topology
• Also called as Superspeed
• Provides power to low power consuming
devices

6. DUAL BUS ARCHITECTURE
• USB 3.0 is a
physical
SuperSpeed
bus combined
in parallel with
a physical USB
2.0 bus

7. SUPER SPEED CONNECTION
Device notifies it is connected
Host makes request
Device ready notifies this with ERDY
Else tells host unavailable to process by sending
NRDY

12. USB 3.0 vs USB2.0
USB 3.0 USB 2.0
•Super speed High speed
•900 mA power 500 mA
•Full duplex Half duplex

13. ADVANTAGES
• Super speed
• Power efficiency
• Efficient when compared to its competitors
• Backward compatibility
DRAWBACKS
• Cable length is limited to 3m.
• Intel at present not supporting
13

14. CONCLUSION
• USB 3.0 wil also be popular like earlier
versions.
• As it is backward compatible it will be used in
the new computers and devices
• High speed communication protocol.
