PRODUCT PREVIEW

USB83340

Highlights

USB-IF Battery Charging 1.1 specification compliant

Link Power Management (LPM) compliant

Integrated ESD protection circuits

Over-Voltage Protection circuit (OVP) protects the

VBUS pin from continuous DC voltages up to 30 V

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

— Extremely low current design ideal for battery powered

applications

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

part in a low current state

— 1.8 V to 3.3 V IO voltage

Single power supply operation

— Integrated 1.8 V regulator

— Integrated battery to 3.3 V regulator

– 100 mV dropout voltage

PHYBoost

— Programmable USB transceiver drive strength for

recovering signal integrity

— Programmable USB receiver sensitivity

“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 an ULPI bridge

External reference clock operation available

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

— 0 to 3.6 V input drive tolerant

— Able to accept “noisy” clock sources as reference to

internal, low-jitter PLL

— Support of multiple frequencies

— Crystal / resonator support

Smart detection circuits allow identification of USB

charger, headset, or data cable insertion

Full support for the optional On-The-Go (OTG)

protocol detailed in the On-The-Go Supplement

Revision 2.0 specification

— Support of the OTG Host Negotiation Protocol (HNP)

and Session Request Protocol (SRP)

UART mode for non-USB serial data transfers

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

and DM lines to VBUS or ground

Environmental

— Automotive grade A temp. support (-40 to +105 °C)

Packaging

— 32-pin, QFN lead-free, RoHS-compliant package

Target Applications
