Introduction ofUSBType-C

• NewgenerationofUSBconnectordeveloped toservethemarketfornext20years

• Thinprofilesuitableforbothultraportabledevicesandlargerdevices

• Reversibleplugorientation&cabledirection– USB3.1Gen2(10Gbps)– USB Powerdelivery,upto100watts– SupportsDisplayPortAlternateMode

USB 3.1 Type-C

USB 3.1 Standard-A

• High speed, secure data• Display connection• System Power

USB Type-C will be the only interface you will need
