����# ���#����

♦ Ease of Use� One interface for many devices� Hot pluggable� Automatic configuration� No power supply required

� Devices can pull up to 500mA from the bus

♦ Reliability� Lossless data transfers

�'

����# ���#����

♦ Speed� Three transfer speeds

� Low Speed – 1.5 Mbps (USB 1.1 and 2.0)� Full Speed – 12 Mbps (USB 1.1 and 2.0)� High Speed – 480 Mbps (USB 2.0 only)� Silicon Labs devices support Low and Full Speed. (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.

�$

)�# � � ��

♦ 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

��

������������

��

)�# � � ��

� 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.

�

����2��� ��) �����

�(

)�# � � ��

♦ 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

�*

����+��������0 2��� ����#�������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

�,

����+��������0 2��� ����#�������+�� ������

♦ 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

�&

����+��������9 5���� ���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

�%

����#�������

♦ Four types of transfers:�Control Transfers�Bulk Transfers� Interrupt Transfers� Isochronous Transfers

�'

����#�������

♦ Control Transfers�Two uses:

� Carry mandatory requests which enable the host to recognize and enumerate devices

� Carry user-defined requests for any other purpose

�Mandatory: Every device must support control transfers�Top Speeds:

� Full Speed – 832 Kbytes/sec

�$

����#�������

♦ Bulk Transfers�Fastest transfer type�No guaranteed data rate or latency�Supported only by High and Full

Speed devices�Top Speeds:

� Full Speed – 1.2 Mbytes/sec

�Common Applications:� Printers� Scanners� Disk Drives (USB thumb drive)

♦ Interrupt Transfers�Guaranteed latency�Top Speeds:

� Full Speed – 64 Kbytes/sec

�Common Applications:� Keyboards� Mice� Joysticks

♦ Isochronous Transfers�Streaming real-time transfers

� Guaranteed delivery rate and latency

� No error correction – Not lossless!

�Supported only by High and Full Speed devices

�Top Speeds:� Full Speed - 1.0 Mbytes/sec

�Common Applications:� Music� Video

♦ TCP/IP is a set of standard communication protocols which fit within the OSI model.

♦ Benefits of TCP/IP:� Interoperability – The protocols operate at a layer of abstraction above the hardware

layer.� Ubiquity – Nearly all network devices implement standard TCP/IP protocols.� Ease of Development – Code implementations are already written and can be

reused.� Reliability – Protocols have been proven by over 20 years of widespread use.

♦ Silicon Laboratories provides a library providing TCP/IP functionality in the Embedded Ethernet Development Kit.

,$

��+?�+�+�������

♦ Network Layer

� IP (Internet Protocol) – Manages logical addressing of network devices (i.e. IP addressing).

� ARP (Address Resolution Protocol) – Converts an IP address (logical address) to a MAC address (physical address).

� PING – Program which sends a packet to a network device and waits for a response. Returns the round trip time of the request.

� UDP (User Datagram Protocol)� Advantages

• Fast• Requires less protocol overhead• Implementations consume less code space

♦ Application Protocols

� HTTP (HyperText Transfer Protocol) – Transfers HTML files across the World Wide Web.
