high-speed inter-chip (hsic) usb 2.0 to 10/100 ethernet controller datasheet smsc lan9730/lan9730i 7 revision 1.1 (05-13-13) datasheet chapter 1 introduction 1.1 block diagram 1.2 overview the lan9730/lan9730i is a high performance solution for usb to 10/100 ethernet port bridging. with applications ranging from embedded systems, set-top boxes, and pvrs, to usb port replicators, and test instrumentation, the device is targeted as a high-performance, lo w-cost usb/ethernet connectivity solution. the lan9730/lan9730i contains an in tegrated 10/100 ethernet phy, hsic interface, hi-speed usb 2.0 device controller, 10/100 etherne t mac, tap controller, eeprom c ontroller, and a fifo controller with a total of 30 kb of internal packet buffering. the internal usb 2.0 device controller is complia nt with the usb 2.0 hi-speed standard. the hsic interface is compliant with the hi gh-speed interchip usb electrical specification revision 1.0. high- speed inter-chip (hsic) is a digital interconnect bus that enables the use of usb technology as a low- power chip-to-chip interconnect at speeds up to 48 0 mb/s. the device implements control, interrupt, bulk-in and bulk-out usb endpoints. the ethernet controller supports auto-negotiation, auto-polarity correction, hp auto-mdix, and is compliant with the i eee 802.3 and 802.3 u standards. an external mii in terface provides support for an external fast ethernet phy, home pna, and homeplug functionality. multiple power management featur es are provided, including various low-power modes, and magic packet, wake on lan and link status change wake events. these wake events can be programmed to initiate a usb remote wakeup. a pci-like pme wake is also supported when the host controller is disabled. an internal eeprom controller exis ts to load various usb configur ation informati on and the device mac address. the integrated ieee 11 49.1 compliant tap controller provides boundar y scan via jtag. figure 1.1 lan9730/lan 9730i block diagram tap controller eeprom controller usb 2.0 device controller sram ethernet phy 10/100 ethernet mac fifo controller hsic interface lan9730/lan9730i mii: to optional external phy ethernet eeprom jtag hsic
high-speed inter-chip (hsic) usb 2.0 to 10/100 ethernet controller datasheet revision 1.1 (05-13-13) 8 smsc lan9730/lan9730i datasheet 1.2.1 usb the usb portion of the lan9730/lan9730i integr ates a hi-speed usb 2.0 device controller and hsic interface. the usb device controller (udc) contains a usb low-level protocol interpreter which implements the usb bus protocol, packet generation/ extraction, pid/device id pars ing and crc coding/decoding, with autonomous error handling. the usb device controller is capable of operating in usb 2.0 hi-speed mode and contains autonomous protocol handling fu nctions such as handling of suspend/resume/reset conditions, remote wakeup, and stall condition clea ring on setup packets. the usb device controller also autonomously handles error conditions such as retry for crc and data toggle errors, and generates nyet, stall, ack a nd nack handshake responses, depending on the endpoint buffer status. the lan9730/lan9730i implements four usb endpoints: control, interrupt, bulk-in, and bulk-out. the bulk-in and bulk-out endpoints allow for ethernet reception and transmission respectively. implementation of vendor-specific commands allows fo r efficient statistics gathering and access to the device?s system control and status registers. the integrated hsic interface is compliant with the high-speed interchip usb electrical specification revision 1.0 (09-23-07) and supports the hi-speed mode of operation. 1.2.2 fifo controller the fifo controller uses an internal sram to buffer rx and tx traffic. bulk-out packets from the usb controller are directly st ored into the tx buffer. ethernet frames are directly stored into the rx buffer and become the basis for bulk-in packets. 1.2.3 ethernet lan9730/lan9730i integrates an ieee 802.3 phy for tw isted pair ethernet applications and a 10/100 ethernet media access controller (mac). the phy can be configured for either 100 mbps (100base-tx) or 10 mbps (10base-t) ethernet operation in either full or half duplex configurat ions. the phy block includes auto-negotiation, auto- polarity correction, and auto-mdix. minimal external components are required for the utilization of the integrated phy. optionally, an external phy may be used via the m ii (media independent interface) port, effectively bypassing the internal phy. this option allows support for homepna and homeplug applications. the ethernet mac/phy supports numerous power management wakeup features, including magic packet, wake on lan and link status change. eight wakeup frame filters are provided by the device.

high-speed inter-chip (hsic) usb 2.0 to 10/100 ethernet controller datasheet revision 1.1 (05-13-13) 38 smsc lan9730/lan9730i datasheet the host processor is connected to a chipset cont aining the usb host controller (hc). the usb host controller interfaces to the device via the hsic usb signals. an embedded controller (ec) signals the chipset and the host processor to power up vi a an enable signal. the ec interfaces to the device via three signals. the pme signal is an input to the ec from the device that indicates the occurrence of a wakeup event. the pme_clear (nreset) signal is used to clear the pme. the pme_mode_sel signal is sampled by the device when pme_clear (nreset) is asserted and is used by the device to determine whether it should remain in pme mode or resume normal operation. gpio pins are used for pme handling. the pins used depend on the value of the phy_sel pin, which determines phy mode of operation. in internal phy mode of operation, gpio0 is reserved for use as an output to signal the pme. gpio1 is reserved for use as the pme_mode_sel input. gpio8 and gpio9 are reserved for analogous use, respec tively, in external phy mode of operation. the application scenario in figure 5.1 assumes that the host processor and the chipset are powered off, the ec is operational, and the device is in pme mode, waiting for a wake event to occur. a wake event will result in the device signaling a pme event to the ec, which will then wake up the host processor and chipset via the enable signal. the ec sets pme_mode_sel to determine whether the device is to begin normal operation or continue in pme mode, and asserts pme_clear (nreset) to clear the pme. the following wake events are supported: ? wakeup pin(s) the gpio pins not reserved for pme handling have the capability to wake up the device when operating in pme mode. in order for a gpio to g enerate a wake event, its enable bit must be set in the gpio10:8 wakeup enables or gpio7:0 wakeup enables bytes of the eeprom, as appropriate. during pme mode of operation, t he gpios used for signaling (gpios 0 and 1 or gpios 8 and 9) are not affected by the values set in the corresponding bits of gpio10:8 wakeup enables or gpio7:0 wakeup enables . gpio10 is available as a wakeup pin in external phy mode, while gpios 2-10 are available in internal phy mode. the gpio10 detection select bit in the gpio pme flags byte of the eeprom sets the detection mode for gpio10 in both external and internal phy mode (if set in gpio10:8 wakeup enables ), while gpios 2-9 are active low (by default) when operating in internal phy mode. ? magic packet reception of a magic packet when in pme mode will result in a pme being asserted. ? phy link up detection of a phy link partner when in pme mode will result in a pme being asserted. in order to facilitate pme mode of operation, the gpio pme enable bit in the gpio pme flags field, must be set and all remaining gpio pme flags field bits must be appropriately configured for pulse or level signaling, buffer type and gpio pme wo l selection. the pme event is signaled on gpio0 (external phy mode) or gpio8, depending on the phy mode of operation. the pme_mode_sel pin (gpio1 in internal m ode of operation, gpio9 in external mode of operation) must be driven to the value that determi nes whether or not the device remains in pme mode of operation (1) or resumes normal operation (0) when the pme is recognized and cleared by the ec via pme_clear (nreset) assertion. note: when in pme mode, nreset or por will always cause the contents of the eeprom to be reloaded. note: gpio10 may be used in pme and external phy mode to connect to an external phy?s link led, in order to generate a phy link up wake event.
