PRODUCT FEATURES
Datasheet
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 to 3.3V IO Voltage (±10%)
Integrated battery to 3.3V 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
Selectable Reference Clock Frequency
— Frequencies: 12, 13, 19.2, 24, 26, 27, 38.4, 52 or
60MHz - pin selectable
External Reference Clock operation available
— 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
Internal Oscillator operation available
— This mode requires external Quartz Crystal or
Ceramic Resonator
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 Headset Audio Mode
Supports the OTG Host Negotiation Protocol (HNP)
and Session Request Protocol (SRP)
UART mode for non-USB serial data transfers
Internal 5V cable short-circuit protection of ID, DP
and DM lines to VBUS or ground
Industrial Operating Temperature -40°C to +85°C
32 pin, QFN Lead-free RoHS Compliant Package
(5 x 5 x 0.90 mm height)
Applications
The USB3320 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 USB3320 is well suited for:
Networking
Audio Video
Medical
Industrial Computers
Printers
Repeaters
Communication
