19. # #
♦ 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
$%

20. # #
♦ 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.
'

21. )#
♦ 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
$

23. )#
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.

24. 2 )

25. )#
♦ 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
(

26. + 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
*

27. + 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
,

28. + 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
&

29. #
♦ Four types of transfers:
Control Transfers
Bulk Transfers
Interrupt Transfers
Isochronous Transfers
%

30. #
♦ 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
'

31. #
♦ 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)
$

32. #
♦ Interrupt Transfers
Guaranteed latency
Top Speeds:
Full Speed – 64 Kbytes/sec
Common Applications:
Keyboards
Mice
Joysticks

33. #
♦ 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

♦ USB defines a set of standard device classes to enable interoperability
across multiple platforms
HID – Human Interface Device
Keyboards, mice, controls, thermometers, voltmeters
Mass Storage
Removable and non-removable storage: floppy, hard, optical, and Flash drives
Audio
Speaker, microphone, audio processor
Communications Device Class
Analog and digital modems, analog and digital telephones, ADSL and cable
modems, ethernet adapters and hubs
IrDA, Power, Printer, Smartcard, Imaging, etc.

35. ) #
♦ The Host machine distinguishes between devices by looking at their
unique identifiers
VID – Vendor ID
Assigned by the USB Implementer’s Forum
PID – Product ID
Assigned by the vendor
Serial Number
Assigned by the developer/manufacturer
Unique for every USB device
♦ Silicon Labs Allotment System
Silicon Labs has a unique VID (0x10C4)
All in-house items are assigned a PID under our VID
Customers may receive PID’s under our VID for bridge and MCU products

♦ 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
♦ Network Layer Path Determination and IP (Logical Addressing )
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.
