USB3300集成電路（IC）的控制器規(guī)格書(shū)PDF中文資料

USB3300屬于集成電路（IC）的控制器。由微芯科技股份有限公司制造生產(chǎn)的USB3300控制器該系列產(chǎn)品主要用于在采用不同通信協(xié)議和/或信令方法的端點(diǎn)之間提供信息連接。示例包括將 I2C 總線(xiàn)連接到 UART，將 USB 連接到 I2C、SPI、以太網(wǎng)或 UART、以太網(wǎng) MAC 和 PHY 等的器件。此外，還包括用于通過(guò)為點(diǎn)對(duì)點(diǎn)通信設(shè)計(jì)的接口建立多路連接的器件，例如 USB 集線(xiàn)器控制器。

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)
