Microchip Technology USB3343-CP-TR

General Description

The USB3300 is an industrial temperature Hi-Speed USB Physical Layer Transceiver (PHY). The USB3300 uses a low pin count interface (ULPI) to connect to a ULPI compliant Link layer. The ULPI interface reduces the UTMI+ interface from 54 pins to 12 pins using a method of in-band signaling and status byte transfers between the Link and PHY.

PRODUCT FEATURES

■ 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
■ 54.7mA Unconfigured Current (typical) - ideal for bus powered applications
■ 83uA suspend current (typical) - ideal for battery powered applications
■ Latch-Up performance exceeds 150 mA per EIA/JESD 78, Class II
■ ESD protection levels of ±8kV HBM without external protection devices
■ Integrated protection to withstand IEC61000-4-2 ESD tests (±8kV contact and ±15kV air) per 3rd party test facility
■ 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
■ Industrial Operating Temperature -40°C to +85°C
■ 32 pin, QFN lead-free RoHS Compliant package (5 x 5 x 0.90 mm height)
