USB3300
Hi-Speed USB Host or
Device PHY with ULPI
Low Pin Interface
PRODUCT FEATURES
Data Brief
■ USB-IF “Hi-Speed” certified to the Universal Serial
Bus Specification Rev 2.0
■ Interface compliant with the ULPI Specification
revision 1.1 in 8-bit mode.
■ Industry standard UTMI+ Low Pin Interface (ULPI.)
Converts 54 UTMI+ signals into a standard 12 pin
Link controller interface.
■ Supports FS pre-amble for FS hubs with a LS device
attached (UTMI+ Level 3)
■ 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.
■ Supports the OTG Host Negotiation Protocol (HNP)
and Session Request Protocol (SRP.)
■ Allows host to turn VBUS off to conserve battery
power in OTG applications.
■ Supports OTG monitoring of VBUS levels with
internal comparators. Includes support for an external
VBUS or fault monitor.
■ Low Latency Hi-Speed Receiver (43 Hi-Speed clocks
Max) allows use of legacy UTMI Links with a ULPI
wrapper.
■ Integrated Pull-up resistor on STP for interface
protection allows a reliable Link/PHY start-up with
slow Links (software configured for low power.)
■ Internal 1.8 volt regulators allow operation from a
single 3.3 volt supply.
■ Internal short circuit protection of ID, DP and DM
lines to VBUS or ground.
■ Integrated 24MHz Crystal Oscillator supports either
crystal operation or 24MHz external clock input.
■ Internal PLL for 480MHz Hi-Speed USB operation.
■ 54.7mA Unconfigured Current (typical) - ideal for bus
powered applications.
■ 83uA suspend current (typical) - ideal for battery
powered applications.
■ Full Commercial operating temperature range from
0C to +70C.
■ 32 pin QFN package; green, lead-free (5 x 5 x 0.90
mm height)
