Hi-Speed USB Host,
Device or OTG PHY with
ULPI Low Pin Interface
Datasheet
PRODUCT FEATURES
USB-IF Hi-Speed certified to the Universal Serial Bus
Specification Rev 2.0
Low Latency Hi-Speed Receiver (43 Hi-Speed clocks
Max) allows use of legacy UTMI Links with a ULPI
wrapper
Interface compliant with the ULPI Specification
revision 1.1 in 8-bit mode
Integrated Pull-up resistor on STP for interface
protection allows a reliable Link/PHY start-up with
slow Links (software configured for low power)
Industry standard UTMI+ Low Pin Interface (ULPI)
Converts 54 UTMI+ signals into a standard 12 pin
Link controller interface
Internal 1.8 volt regulators allow operation from a
single 3.3 volt supply
54.7mA Unconfigured Current (typical) - ideal for bus
powered applications
Internal short circuit protection of ID, DP and DM
lines to VBUS or ground
83uA suspend current (typical) - ideal for battery
powered applications
Integrated 24MHz Crystal Oscillator supports either
crystal operation or 24MHz external clock input
Latch-Up performance exceeds 150 mA per
EIA/JESD 78, Class II
Internal PLL for 480MHz Hi-Speed USB operation
ESD protection levels of ±8kV HBM without external
protection devices
Industrial Operating Temperature -40°C to +85°C
32 pin QFN package; green, lead-free (5 x 5 x 0.90
mm height)
Integrated protection to withstand IEC61000-4-2 ESD
tests (±8kV contact and ±15kV air) per 3rd party test
facility
APPLICATIONS
Supports FS pre-amble for FS hubs with a LS device
attached (UTMI+ Level 3)
The USB3300 is the ideal companion to any ASIC, SoC
or FPGA solution designed with a ULPI Hi-Speed USB
host, peripheral or OTG core.
Supports HS SOF and LS keep-alive pulse
Includes full support for the optional On-The-Go
(OTG) protocol detailed in the On-The-Go
Supplement Revision 1.0a specification
The USB3300 is well suited for:
Cell Phones
PDAs
Supports the OTG Host Negotiation Protocol (HNP)
and Session Request Protocol (SRP)
MP3 Players
Allows host to turn VBUS off to conserve battery
power in OTG applications
Scanners
External Hard Drives
Digital Still and Video Cameras
Portable Media Players
Printers
Supports OTG monitoring of VBUS levels with
internal comparators. Includes support for an external
VBUS or fault monitor.
