(USB 2.0 Compliant) ♦ Low Power Consumption Suspend mode Devices consume 500 A or less ♦ Availability Microsoft and Intel’s PC 2001 System Design Guide requires that all new PC’s have two user-accessible USB ports. '
  • 19. )# ♦ USB – Universal Serial Bus ♦ Host – System which initiates all transfers over the bus ♦ Device – Peripheral which communicates with and receives information from the host ♦ Hub – Provides connecting points and power ♦ Pipe – Logical abstraction which creates an association between an endpoint on a device and the host software ♦ Endpoint – Memory buffer on a device which serves as a sink or source of data IN Endpoint – Endpoint from which host reads data OUT Endpoint – Endpoint to which host writes data Endpoints on Silicon Labs MCUs are implemented as FIFO’s in on-chip XRAM $
  • 20. )# Transfer – The process of making and carrying out a communication request Transaction – The delivery of service to an endpoint Packet – Block of information Frame – A 1 ms time base established on low- and full-speed buses ♦ Transfers are divided into transactions. ♦ Transactions are made up of packets. ♦ The host controls transfers by allocating transactions to a frame. ♦ Transfers may span multiple frames.
  • 21. 2 )
  • 22. )# ♦ Enumeration Enumeration is the activity that identifies and assigns unique addresses to devices attached to a bus Makes USB devices hot-pluggable The host is always checking the bus for new devices The host cannot communicate with a USB device until that device has been properly enumerated Invisible to user (
  • 23. + 02 # 1 ♦ Enumerate Devices ♦ Transfer Data with Peripherals ♦ Provide Power A full-power USB Host can provide up to 500 mA for each peripheral Some low-power USB hosts support only low-power devices which are limited to 100 mA USB peripherals can be self-powered as well ♦ Manage the USB Bus *
  • 24. + 02 # + ♦ Transfer Data with the USB Host ♦ Manage power The supply current that can be drawn from the bus depends on the state of the bus A bus-powered device in normal mode may draw up to 500 mA When the bus is suspended, the device must draw less than 500 uA If the device supports remote wakeup, it may draw up to 2.5 mA when in suspend mode ♦ Respond to Standard Requests from the Host ,
  • 25. + 95 7+ ♦ All data is transferred to or from a device endpoint ♦ An Endpoint is memory on the USB peripheral that stores the data it receives from the host or it stores the data it intends to send ♦ Endpoints transfer data in one direction and labeled either IN or OUT, except for control endpoints which are bidirectional ♦ A Pipe is a logical connection between an endpoint on the device and the host controller’s software &
  • 26. # ♦ Four types of transfers: Control Transfers Bulk Transfers Interrupt Transfers Isochronous Transfers %
