SMSC USB3316 REV

Hi-Speed USB Transceiver with 1.8V ULPI Interface - 19.2MHz Reference Clock
General Description
The USB3316 is a highly integrated Hi-Speed USB 2.0 Transceiver (PHY) that supports systems
architectures based on a 19.2MHz reference clock. It is designed to be used in both commercial and
industrial temperature applications.
The USB3316 meets all of the electrical requirements to be used as a Hi-Speed USB Host, Device,
or an On-the-Go (OTG) device. In addition to the supporting USB signaling the USB3316 also provides
USB UART mode and USB Audio mode.
USB3316 uses the industry standard UTMI+ Low Pin Interface (ULPI) to connect the USB PHY to the
Link. The industry standard ULPI interface uses a method of in-band signaling and status byte transfers
between the Link and PHY, to facilitate a USB session. By using in-band signaling and status byte
transfers the ULPI interface requires only 12 pins.
The USB3316 uses SMSC’s “wrapper-less” technology to implement the ULPI interface. This “wrapper-
less” technology allows the PHY to achieve a low latency transmit and receive time. SMSC’s low
latency transceiver allows an existing UTMI Link to be reused by adding a UTMI to ULPI bridge. By
adding a bridge to the ASIC the existing and proven UTMI Link IP can be reused.

Revision 2.1 (06-10-10)
Hi-Speed USB Transceiver with 1.8V ULPI Interface - 19.2MHz Reference Clock
The USB3316 is designed to run with a 19.2MHz reference clock. By using a reference clock from the
Link the USB3316 is able to remove the cost of a crystal reference from the design.
The USB3316 includes a integrated 3.3V LDO regulator to generate its own supply from power applied
at the
VBAT
pin. The voltage on the
VBAT
pin can range from 3.1 to 5.5V. The regulator dropout
voltage is less than 100mV which allows the PHY to continue USB signaling when the voltage on
VBAT
drops to 3.1V. The USB transceiver will continue to operate at lower voltages, although some
parameters may be outside the limits of the USB specifications. If the user would like to provide a 3.3V
supply to the USB3316, the
VBAT
and
VDD33
pins should be connected together.
The USB3316 also includes integrated pull-up resistors that can be used for detecting the attachment
of a USB Charger. By sensing the attachment to a USB Charger, a product using the USB3316 can
charge its battery at more than the 500mA allowed when charging from a USB Host.
The USB3316 also includes support for USB audio modes. The user can program the PHY into UART
or audio mode while in synchronous mode.
In USB UART mode, the USB3316
DP
and
DM
pins are redefined to enable pass-through of
asynchronous serial data. The USB3316 can only enter UART mode when the user programs the part
into this mode.
In USB audio mode, the
DP
pin is shorted to the
SPKR_R/M
pin with a switch. The
DM
pin is shorted
to the
SPKR_L
pin. These switches are on when the
RESETB
pin of the USB3316 is asserted. Audio
signals may be transferred over the USB cable. In addition to audio signals, the switches can also be
used to connect Full Speed USB from another PHY onto the USB cable.
