USB332x

Industry’s Smallest Hi-Speed USB

Transceiver with 1.8V ULPI Interface

PRODUCT FEATURES

Integrated ESD protection circuits

— Up to ±15kV IEC Air Discharge without external

devices

Over-Voltage Protection circuit (OVP) protects the

VBUS pin from continuous DC voltages up to 30V

Integrated USB Switch

— No degradation of Hi-Speed electrical

characteristics

— Allows single USB port of connection by

providing switching function for:

– Battery charging

– Stereo and mono/mic audio

– USB Full-Speed/Low-Speed data

flexPWR

Technology

— Low current design ideal for battery powered

applications

— “Sleep” mode tri-states all ULPI pins and places

the part in a low current state

— 1.8V IO Voltage (±10%)

Integrated battery to 3.3V LDO regulator

— 2.2uF bypass capacitor

— 100mV dropout voltage

“Wrapper-less” design for optimal timing performance

and design ease

— Low Latency Hi-Speed Receiver (43 Hi-Speed

clocks Max) allows use of legacy UTMI Links with

a ULPI bridge

External Reference Clock operation

— ULPI Input Clock Mode (60MHz sourced by Link)

— 0 to 3.6V input drive tolerant

— Able to accept “noisy” clock sources as reference

to internal, low-jitter PLL

— Frequencies: 12, 13, 19.2, 26, or 27MHz

Smart detection circuits allow identification of USB

charger, headset, or data cable insertion

Includes full support for the optional On-The-Go

(OTG) protocol detailed in the On-The-Go

Supplement Revision 2.0 specification

Supports the OTG Host Negotiation Protocol (HNP)

and Session Request Protocol (SRP)

UART mode for non-USB serial data transfers

SMSC USB332x

Datasheet

Internal 5V cable short-circuit protection of ID, DP

and DM lines to VBUS or ground

Industrial Operating Temperature -40°C to +85°C

25 ball WLCSP lead-free RoHS compliant package;

(2.0 x 2.0 x 0.53mm height)

Applications

The USB332x is targeted for any application where a Hi-

Speed USB connection is desired and when board

space, power, and interface pins must be minimized.

The USB332x is well suited for:

Cell Phones

PDAs

MP3 Players
