1 / 11 page ![]() SMSC USB3300 PRODUCT PREVIEW Revision 1.02 (02-16-05) Data Brief PRODUCT FEATURES USB3300 Hi-Speed USB Host or Device PHY with ULPI Low Pin Interface ■ 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) |
