USB3503A-1-GL-TR - Brand New Microchip Technology Network Interface Card (NIC)
-
Description
The USB3503A-1-GL-TR is a network interface card (NIC) component model that features a Hi-Speed USB Physical Layer Transceiver (PHY). It 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 in-band signaling and status byte transfers between the Link and PHY.
Specifications and 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)
Application Scenarios
The USB3503A-1-GL-TR is the ideal companion to any ASIC, SoC or FPGA solution designed with a ULPI Hi-Speed USB host, peripheral, or OTG core. It is well suited for various devices including cell phones, PDAs, MP3 players, scanners, external hard drives, digital still and video cameras, portable media players, and printers.
