Chapter 1 General Description
SMSC USB3300
ULPI
LINK
The USB3300 is an industrial temperature Hi-Speed USB Physical Layer Transceiver (PHY). The
USB3300 uses a low pin count interface (ULPI) to connect to a ULPI compliant Link layer. The ULPI
interface reduces the UTMI+ interface from 54 pins to 12 pins using a method of in-band signaling and
status byte transfers between the Link and PHY.
This PHY was designed from the start with the ULPI interface. No UTMI to ULPI wrappers are used
in this design which provides a seamless ULPI to Link interface. The result is a PHY with a low latency
transmit and receive time. SMSC’s low latency high speed and full speed receiver provide the option
of re-using existing UTMI Links with a simple wrapper to convert UTMI to ULPI.
The ULPI interface allows the USB3300 PHY to operate as a device, host, or an On-The-Go (OTG)
device. Designs using the USB3300 PHY as a device, can add host and OTG capability at a later date
with no additional pins.
The ULPI interface, combined with SMSC’s proprietary technology, makes the USB3300 the ideal
method of adding Hi-Speed USB to new designs. The USB3300 features an industry leading small
footprint package (5mm by 5mm) with sub 1mm height. In addition the USB3300 integrates all DP and
DM termination resistances and requires a minimal number of external components.
The ULPI interface consists of 12 interface pins; 8 bi-directional data pins, 3 control pins, and a 60
MHz clock. By using the 12 pin ULPI interface the USB3300 is able to provide support for the full range
of UTMI+ Level 3 through Level 0, as shown in
FS peripheral and as a HS, FS, and LS Host.
The USB3300 can also, as an option, fully support the On-the-Go (OTG) protocol defined in the On-
The-Go Supplement to the USB 2.0 Specification. On-the-Go allows the USB3300 to function like a
host, or peripheral configured dynamically by software. For example, a cell phone may connect to a
computer as a peripheral to exchange address information or connect to a printer as a host to print
pictures. Finally the OTG enabled device can connect to another OTG enabled device to exchange
information. All this is supported using a single low profile Mini-AB USB connector.
Designs not needing OTG can ignore the OTG feature set.
In addition to the advantages of the leading edge ULPI interface, the use of SMSC’s advanced analog
technology enables the USB3300 to consume a minimum amount of power which results in maximized
battery life for portable applications.
