Industry’s Smallest Hi-Speed USB Transceiver with 1.8V ULPI Interface
SMSC USB332x

Revision 1.1 (03-31-10)
PRODUCT PREVIEW
General Description
SMSC’s USB332x is a family of Hi-Speed USB 2.0 Transceivers that provides a physical layer (PHY)
solution well-suited for portable electronic devices. Both commercial and industrial temperature
applications are supported.
Each model in the USB332x family may use a 60MHz reference clock, or the model-number specific
reference clock shown in Order Numbers on page 2.
Several advanced features make the USB332x the transceiver of choice by reducing both electrical
bill of material (eBOM) part count and printed circuit board (PCB) area. Outstanding ESD robustness
eliminates the need for external ESD protection devices in typical applications. The internal Over-
Voltage Protection circuit (OVP) protects the USB332x from voltages up to 30V. By using a reference
clock from the Link, the USB332x removes the cost of a dedicated crystal reference from the design.
And the integrated USB switch enables unique product features with a single USB port of connection.
The USB332x meets all of the electrical requirements to be used as a Hi-Speed USB Host, Device, or
an On-the-Go (OTG) transceiver. In addition to the supporting USB signaling, the USB332x also
provides USB UART mode and USB Audio mode.
USB332x uses the industry standard UTMI+ Low Pin Interface (ULPI) to connect the USB PHY to the
Link. ULPI uses a method of in-band signaling and status byte transfers between the Link and PHY to
facilitate a USB session with only 12 pins.
The USB332x 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.
