With applications ranging from embedded systems, desktop PCs, notebook PCs, printers, game consoles, and docking stations, the LAN9514/LAN9514i is targeted as a high performance, low cost USB/Ethernet and USB/USB connectivity solution. The LAN9514/LAN9514i contains an integrated USB 2.0 hub, four integrated downstream USB 2.0 PHYs, an integrated upstream USB 2.0 PHY, a 10/100 Ethernet PHY, a 10/100 Ethernet Controller, a TAP controller, and a EEPROM controller. A block diagram of the LAN9514/LAN9514i is provided in Figure 1.1. The LAN9514/LAN9514i hub provides over 30 programmable features, including: PortMap ( also referred to as port remap) which provides flexible port mapping and disabling sequences. The downstream ports of the LAN9514/LAN9514i hub can be reordered or disabled in any sequence to support multiple platform designs’ with minimum effort. For any port that is disabled, the LAN9514/LAN9514i automatically reorders the remaining ports to match the USB host controller’s port numbering scheme. PortSwap which adds per-port programmability to USB differential-pair pin locations. PortSwap allows direct alignment of USB signals (D+/D-) to connectors avoiding uneven trace length or crossing of the USB differential signals on the PCB. PHYBoost which enables four programmable levels of USB signal drive strength in USB port transceivers. PHYBoost attempts to restore USB signal integrity that has been compromised by system level variables such as poor PCB layout, long cables, etc.. Revision 1.0 (11-24-09) DATASHEET 6 SMSC LAN9514/LAN9514i USB 2.0 Hub and 10/100 Ethernet Controller Datasheet 1.1.2 USB Hub The integrated USB hub is fully compliant with the USB 2.0 Specification and will attach to a USB host as a Full-Speed Hub or as a Full-/High-Speed Hub. The hub supports Low-Speed, Full-Speed, and High-Speed (if operating as a High-Speed hub) downstream devices on all of the enabled downstream ports. A dedicated Transaction Translator (TT) is available for each downstream facing port. This architecture ensures maximum USB throughput for each connected device when operating with mixed-speed peripherals. The hub works with an external USB power distributed switch device to control VBUS switching to downstream ports, and to limit current and sense over-current conditions. All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D- pins and all required pull-down and pull-up resistors on D+ and D- pins. The over-current sense inputs for the downstream facing ports have internal pull-up resistors. Four external ports are available for general USB device connectivity. 1.1.3 Ethernet Controller The 10/100 Ethernet controller provides an integrated Ethernet MAC and PHY which are fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant. The 10/100 Ethernet controller also supports numerous power management wakeup features, including “Magic Packet”, “Wake on LAN” and “Link Status Change”. These wakeup events can be programmed to initiate a USB remote wakeup. The 10/100 Ethernet PHY integrates an IEEE 802.3 physical layer for twisted pair Ethernet applications. The PHY block includes support for auto-negotiation, full or half-duplex configuration, auto-polarity correction and Auto-MDIX. Minimal external components are required for the utilization of the integrated PHY. The Ethernet controller 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 Ethernet controller’s system control and status registers. 1.1.4 EEPROM Controller The LAN9514/LAN9514i contains an EEPROM controller for connection to an external EEPROM. This allows for the automatic loading of static configuration data upon power-on reset, pin reset, or software reset. The EEPROM can be configured to load USB descriptors, USB device configuration, and the MAC address. 1.1.5 Peripherals The LAN9514/LAN9514i also contains a TAP controller, and provides three PHY LED indicators, as well as eight general purpose I/O pins. All GPIOs can serve as remote wakeup events when LAN9514/LAN9514i is in a suspended state. The integrated IEEE 1149.1 compliant TAP controller provides boundary scan via JTAG. 1.1.6 Power Management The LAN9514/LAN9514i features three variations of USB suspend: SUSPEND0, SUSPEND1, and SUSPEND2. These modes allow the application to select the ideal balance of remote wakeup functionality and power consumption. SUSPEND0: Supports GPIO, “Wake On LAN”, and “Magic Packet” remote wakeup events. This suspend state reduces power by stopping the clocks of the MAC and other internal modules.

Port Power Control Using a USB Power Switch The LAN9514/LAN9514i has a single port power control and over-current sense signal for each downstream port. When disabling port power the driver will actively drive a ‘0’. To avoid unnecessary power dissipation, the internal pull-up resistor will be disabled at that time. When port power is enabled, the output driver is disabled and the pull-up resistor is enabled, creating an open drain output. If there is an over-current situation, the USB Power Switch will assert the open drain OCS signal. The schmitt trigger input will recognize this situation as a low. The open drain output does not interfere. The overcurrent sense filter handles the transient conditions, such as low voltage, while the device is powering up. 5V 5V OCS PRTCTL4 PRTCTL3 OCS USB Power Switch EN USB Power Switch EN USB Device LAN9514/ LAN9514i USB Device 5V 5V OCS PRTCTL5 PRTCTL2 OCS USB Power Switch EN USB Power Switch EN USB Device USB Device Figure 2.2 Port Power Control with USB Power Switch Revision 1.0 (11-24-09) DATASHEET 16 SMSC LAN9514/LAN9514i USB 2.0 Hub and 10/100 Ethernet Controller Datasheet 2.1.2 Port Power Control Using a Poly Fuse When using the LAN9514/LAN9514i with a poly fuse, an external diode must be used (See Figure 2.3). When disabling port power, the driver will drive a ‘0’. This procedure will have no effect since the external diode will isolate the pin from the load. When port power is enabled, the output driver is disabled and the pull-up resistor is enabled, which creates an open drain output. This means that the pull-up resistor is providing 3.3 volts to the anode of the diode. If there is an over-current situation, the poly fuse will open. This will cause the cathode of the diode to go to 0 volts. The anode of the diode will be at 0.7 volts, and the Schmidt trigger input will register this as a low, resulting in an overcurrent detection. The open drain output does not interfere. 5V 5V Poly Fuse Poly Fuse PRTCTL4 PRTCTL3 USB Device USB Device LAN9514/ LAN9514i 5V 5V Poly Fuse Poly Fuse PRTCTL5 PRTCTL2 USB Device USB Device Figure 2.3 Port Power Control with Poly Fuse SMSC LAN9514/LAN9514i DATASHEET 17 Revision 1.0 (11-24-09) USB 2.0 Hub and 10/100 Ethernet Controller Datasheet Many customers use a single poly fuse to power all their devices.

The EEPROM controller supports most “93C46” type EEPROMs. A total of nine address bits are used to support 256/512 byte EEPROMs. Note: A 3-wire style 2K/4K EEPROM that is organized for 256/512 x 8-bit operation must be used. The MAC address is used as the default Ethernet MAC address and is loaded into the MAC’s ADDRH and ADDRL registers. If a properly configured EEPROM is not detected, it is the responsibility of the Host LAN Driver to set the IEEE addresses. After a system-level reset occurs, the device will load the default values from a properly configured EEPROM. The device will not accept USB transactions from the Host until this process is completed. The EEPROM controller also allows the Host system to read, write and erase the contents of the Serial EEPROM. 3.1 EEPROM Format Table 3.1 illustrates the format in which data is stored inside of the EEPROM. Note the EEPROM offsets are given in units of 16-bit word offsets. A length field with a value of zero indicates that the field does not exist in the EEPROM. The device will use the field’s HW default value in this case. Note: For Device Descriptors, the only valid values for the length are 0 and 18. Note: For Configuration and Interface Descriptors, the only valid values for the length are 0 and 18. Note: The EEPROM programmer must ensure that if a String Descriptor does not exist in the EEPROM, the referencing descriptor must contain 00h for the respective string index field. Note: If no Configuration Descriptor is present in the EEPROM, then the Configuration Flags affect the values of bmAttributes and bMaxPower in the Ethernet Controller Configuration Descriptor. Note: If all String Descriptor lengths are zero, then a Language ID will not be supported.

The hub is not permitted to select a numerical range or assignment. The Host Controller will number the downstream ports of the hub starting with the number 1, up to the number of ports that the hub reported having. The host’s port number is referred to as “Logical Port Number” and the physical port on the hub is the “Physical Port Number”. When remapping mode is enabled, (see Port Re-Mapping Enable (PRTMAP_EN) bit in Config Data Byte 3 Register (CFG3) Format) the hub’s downstream port numbers can be remapped to different logical port numbers (assigned by the host). Note: The OEM must ensure that Contiguous Logical Port Numbers are used, starting from #1 up to the maximum number of enabled ports. This ensures that the hub’s ports are numbered in accordance with the way a Host will communicate with the ports.

When configured as a Bus-Powered device, the SMSC Hub consumes less than 100mA of current prior to being configured. After configuration, the BusPowered SMSC Hub (along with all associated hub circuitry, any embedded devices if part of a compound device, and 100mA per externally available downstream port) must consume no more than 500mA of upstream VBUS current. The current consumption is system dependent, and the OEM must ensure that the USB2.0 specifications are not violated. When configured as a Self-Powered device,
