hi-speed usb 2.0 to 10/100/1000 ethernet controllerdatasheet ? 2014 microchip technology inc. ds00001734a-page 7 chapter 1 introduction 1.1 block diagram 1.1.1 overview the lan7500/lan7500i is a high performance hi-speed usb 2.0 to 10/100/1000 ethernet controller. with applications ranging from embedded systems, set-top boxes, and pvrs, to usb port replicators, usb to ethernet dongles, and test instrumentation, the device is a high performance and cost competitive usb to ethernet connectivity solution. the lan7500/lan7500i contains an integrated 10/100/1000 ethernet mac and phy, filtering engine, usb phy, hi-speed usb 2.0 device controller, tap controller, eeprom controller, and a fifo controller with a total of 32 kb of internal packet buffering. the internal usb 2.0 device controller and usb phy are compliant with the usb 2 .0 hi-speed standard. 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 ieee 802.3, ieee 802.3u, ieee 802.3ab standards. arp and ns offload is also supported. multiple power management features 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. an internal eeprom controller exists to load various usb configuration information and the device mac address. the integrated ieee 1149.1 compliant tap controller provides boundary scan via jtag. figure 1.1 lan7500/lan7500i system diagram downloaded from: http:///
hi-speed usb 2.0 to 10/100/1000 ethernet controller datasheet ds00001734a-page 8 ? 2014 microchip technology inc 1.1.2 usb the usb portion of the lan7500/lan7500i integrates a hi-speed usb 2.0 device controller and usb phy. the usb device controller contains a usb low-level protocol interpreter which implements the usb bus protocol, packet generation/extraction, pid/de vice id parsing, and crc coding/decoding, with autonomous error handling. the usb device controller is capable of operating in usb 2.0 hi-speed and full-speed compliant modes and contains autonomous protocol handling functions such as handling of suspend/resume/reset conditions, remote wakeup, and stall condition clearing 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 and nack handshak e responses, depending on the endpoint buffer status. the lan7500/lan7500i 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 for efficient statistics gathering and access to the devices system control and status registers. 1.1.3 fifo controller the fifo controller uses two internal srams to buffer rx and tx traffic. bulk-out packets from the usb controller are directly stored into the tx buffer. the fifo controller is responsible for extracting ethernet frames from the usb packet data and passing the frames to the mac. received ethernet frames are filtered by the receive filtering engine and frames meeting the filtering constraints are stored into the rx buffer and become the basis for bulk-in packets. 1.1.4 ethernet the lan7500/lan7500i integrates an ieee 802.3/802.3u/802.3ab compliant phy for twisted pair ethernet applications and a 10/100/1000 ethernet media access controller (mac). the phy can be configured for 1000 mbps (1 000base-t), 100 mbps (1 00base-tx) or 10 mbps (10base-t) operation in full-duplex mode. it can be configured for 100 mbps or 10 mbps operation in half duplex mode. the phy block includes auto -negotiation, auto-polarity correction, and auto- mdix. minimal external components are required for the utilization of the integrated phy. the ethernet mac/phy supports numerous power management wakeup features, including magic packet, wake on lan, and link status change. microsoft ndis 6.2 and windows 7 compliant arp and ns offload support is also provided.the device will respond to an ns or arp request by generating and transmitting a response. when received in a suspend state, an ns or arp request will not result in the generation of a wake event. additionally, five status leds are supported. 1.1.5 frame filtering the lan7500/lan7500i receive filtering engine performs frame filtering. it supports 33 perfect address filters. these can be used to filter either the ethernet source address or destination address. additional address filtering is available via a 512-bit hash filter. the hash filter can perform unicast or multicast filtering. vlan tagged frames can be filtered via the vlan id. a 4096-bit table exists to support all possible vlan ids. the vlan type can be programmed. double tagging is supported. downloaded from: http:///
hi-speed usb 2.0 to 10/100/1000 ethernet controllerdatasheet ? 2014 microchip technology inc. ds00001734a-page 9 1.1.6 host offloading the lan7500/lan7500i supports a variety of tcp/udp/ip checksum offloads to reduce the burden on the host processor. for ethernet receive frames, the device can be configured to validate the ip checksum and udp/tcp checksum. both ipv4 and ipv6 packets are supported. a raw checksum across the layer 3 packet can also be provided. for ethernet transmitted frames, the device can be configured to calculate the ip checksum and udp/tcp checksum. additionally, large send offload (lso) is supported to further reduce host cpu loading. 1.1.7 power management the lan7500/lan7500i features four variations of usb suspend: suspend0, suspend1, suspend2, and suspend3. these modes allow the application to select the ideal balance of remote wakeup functionality and power consumption. ? suspend0: supports gpio, wake on lan, magic packet, and phy link up remote wakeup events. it, however, consumes the most power. ? suspend1: supports gpio and link status change for remote wakeup events. this suspend state consumes less power than suspend0. ? suspend2: supports only gpio assertion for a remote wakeup event. this is the default suspend mode for the device. ? suspend3: supports gpio, good packet, and phy link up remote wakeup events. a good packet is a received frame that is free of errors and passes certain filtering constraints independent of those imposed on wake on lan and magic packet frames. this suspend state consumes power at a level similar to the normal state, however, it allows for power savings in the host cpu, which greatly exceeds that of the lan7500/lan7500i. the driver may place the device in this state after prolonged periods of not receiving any ethernet traffic. 1.1.8 eeprom controller the lan7500/lan7500i contains an eeprom controller for connection to an external eeprom. this allows for the automatic loading of static configuration data upon pin reset, or software reset. the eeprom can be configured to load usb descriptors, usb device configuration, and mac address. custom operation without eeprom is also provided. 1.1.9 general purpose i/o twelve gpios are supported. all gpios can serve as remote wakeup events when the lan7500/lan7500i is in a suspended state. 1.1.10 tap controller ieee 1149.1 compliant tap controller supports boundary scan and various test modes. the device includes an integrated jtag boundary-scan test port for board-level testing. the interface consists of four pins (tdo, tdi, tck and tms) and includes a state machine, data register array, and an instruction register. the jtag pins are described in table 2.3, jtag pins, on page 14 . the jtag interface conforms to the ieee standard 1149.1 - 1990 standard test access port (tap) and boundary-scan architecture . all input and output data is synchronous to the tck test clock input. tap input signals tms and tdi are clocked into the test logic on the rising edge of tck, while the output signal tdo is clocked on the falling edge. the jtag logic is reset when the tms and tdi pins are high for five tck periods. downloaded from: http:///

hi-speed usb 2.0 to 10/100/1000 ethernet controllerdatasheet ? 2014 microchip technology inc. ds00001734a-page 31 the host processor is connected to a chipset containing the host usb controller (hc). the usb host controller interfaces to lan7500/lan7500i via the dp/dm usb signals. an embedded controller (ec) signals the chipset and the host processor to power up via an enable signal. the ec interfaces to lan7500/lan7500i via four signals. the pme signal is an input to the ec from the device that indicates the occurrence of a wakeup event. the vbus_det output of the ec is used to indicate bus power availability. 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. gpio5 is reserved for use as an output to signal the pme. gpio6 is reserved for use as the pme_mode_sel input. the application scenario in figure 4.1 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 asserts vbus_det after the usb bus is powered, sets pme_mode_sel to determine whethe r 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 generate a wake event, its enable bit must be set in the gpi0[11:8] wakeup enables or gpio[7:0] wakeup enables bytes of the eeprom, as appropriate. during pme mode of operation, the gpios used for signaling ( gpio5 and gpio6 ) are not affected by the values set in the corresponding bits of gpio[7:0] wakeup enables . gpios 0 - 4 and 7 - 10 are available as wakeup pins in pme mode of operation and are active low by default. ? magic packet reception of a magic packet when in pme mode will result in a pme being asserted. ? perfect da match of physical address reception of an ethernet frame whose destination address matches the devices mac address 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 wol selection. the pme event is signaled on gpio5 . the pme_mode_sel pin ( gpio6 ) must be driven to the value that determines 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 or nreset will always cause the contents of the eeprom to bereloaded. downloaded from: http:///
