DATASHEET
Chapter 1 Introduction
1.1 Block Diagram
1.1.1 Overview
The LAN9514/LAN9514i is a high performance Hi-Speed USB 2.0 hub with a 10/100 Ethernet
controller. 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.

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.
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 LAN9514/LAN9514i.

2.2 Port Power Control
This section details the usage of the port power control pins PRTCTL[5:2].
2.2.1 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.

2.2.2 Port Power Control Using a Poly Fuse
When using the LAN9514/LAN9514i with a poly fuse, an external diode must be used (See Figure 2.4).
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.

Chapter 3 EEPROM Controller (EPC)
LAN9514/LAN9514i may use an external EEPROM to store the default values for the USB descriptors
and the MAC address. 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.

7Self or Bus Power (SELF_BUS_PWR)
Selects between Self or Bus-Powered operation.
0 = Bus-Powered
1 = Self-Powered
The Hub is either Self-Powered (draws less than 2mA of upstream bus power) or Bus-
Powered (limited to a 100mA maximum of upstream power prior to being configured
by the host controller).
When configured as a Bus-Powered device, the SMSC Hub consumes less than
100mA of current prior to being configured. After configuration, the Bus-Powered
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, <1mA of upstream VBUS current is
consumed and all ports are available, with each port being capable of sourcing 500mA
of current.

4Multiple TT Enable (MTT_ENABLE)
Enables one transaction translator per port operation.
Selects between a mode where only one transaction translator is available for all ports
(Single-TT), or each port gets a dedicated transaction translator (Multi-TT) {Note: The
host may force Single-TT mode only}.
0 = Single TT for all ports.
1 = One TT per port (multiple TT's supported)
1b
3EOP Disable (EOP_DISABLE)
Disables EOP generation of EOF1 when in Full-Speed mode. During FS operation
only, this permits the Hub to send EOP if no downstream traffic is detected at EOF1.
See Section 11.3.1 of the USB 2.0 Specification for additional details.
Note: Generation of an EOP at the EOF1 point may prevent a Host controller
(operating in FS mode) from placing the USB bus in suspend.
0 = An EOP is generated at the EOF1 point if no traffic is detected.
1 = EOP generation at EOF1 is disabled (note: this is normal USB operation).
Note: This is a rarely used feature in the PC environment, existing drivers may not
have been thoroughly debugged with this feature enabled. It is included
because it is a permitted feature in Chapter 11 of the USB specification.

3.2 EEPROM Defaults
The signature value of 0xA5 is stored at address 0. A different signature value indicates to the
EEPROM controller that no EEPROM or an un-programmed EEPROM is attached to the device. In
this case, the hardware default values are used, as shown in Table 3.11 .
3.3 EEPROM Auto-Load
Certain system level resets (USB reset, POR, nRESET, and SRST) cause the EEPROM contents to
be loaded into the device. After a reset, the EEPROM controller attempts to read the first byte of data
from the EEPROM. If the value 0xA5 is read from the first address, then the EEPROM controller will
assume that the external Serial EEPROM is configured for auto-loading. If a value other than 0xA5 is
read from the first address, the EEPROM auto-load will not commense.
Note: The EEPROM contents are loaded for both the Hub and the Ethernet Controller as a result of
a POR or nRESET. The USB reset results only in the loading of the MAC address from the
EEPROM. A software reset (SRST) or a EEPROM Reload Command causes the EEPROM
contents related solely to the Ethernet Controller to be loaded.

4.6 Clock Circuit
LAN9514/LAN9514i can accept either a 25MHz crystal (preferred) or a 25MHz single-ended clock
oscillator (+/- 50ppm) input. If the single-ended clock oscillator method is implemented, XO should be
left unconnected and XI should be driven with a nominal 0-3.3V clock signal. The input clock duty cycle
is 40% minimum, 50% typical and 60% maximum.
It is recommended that a crystal utilizing matching parallel load capacitors be used for the crystal
input/output signals (XI/XO). See Table 4.10 for the recommended crystal specifications.
Note 4.13 The maximum allowable values for Frequency Tolerance and Frequency Stability are
application dependant. Since any particular application must meet the IEEE +/-50 PPM
Total PPM Budget, the combination of these two values must be approximately +/-45 PPM
(allowing for aging).
Note 4.14 Frequency Deviation Over Time is also referred to as Aging.
Note 4.15 The total deviation for the Transmitter Clock Frequency is specified by IEEE 802.3u as
+/- 50 PPM.
Note 4.16 0oC for commercial version, -40oC for industrial version.
Note 4.17 +70oC for commercial version, +85oC for industrial version.
Note 4.18 This number includes the pad, the bond wire and the lead frame. PCB capacitance is not
included in this value. The XO/XI pin and PCB capacitance values are required to
accurately calculate the value of the two external load capacitors. These two external load
capacitors determine the accuracy of the 25.000 MHz frequency.
