PRODUCT FEATURES
USB2513i
Industrial Temperature
Rated USB 2.0 High-Speed
3-Port Hub Controller
General Description
The SMSC 3-Port Hub is low power, OEM configurable,
MTT (multi transaction translator) hub controller IC with
3 downstream ports for embedded USB solutions. The
3-port hub is fully compliant with the USB 2.0
Specification and will attach to an upstream port as a
Full-Speed Hub or as a Full-/High-Speed Hub. The 3-
Port 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.
General Features
Hub Controller IC with 3 downstream ports
High-performance multiple transaction translator
MultiTRAK™ Technology Provides one transaction
translator per port

through either a single serial i2C EEPROM, or
SMBus Slave Port
36-pin (6x6mm) and 48-Pin (7x7mm) QFN lead-free,
RoHS compliant packages
Footprint compatible with USB2514i and USB2512i
(36-pin QFN) to provide designers with flexibility
regarding the quantity of USB expansion ports
utilized without redesign
Supports industrial temperature range of -40ºC to
85ºC
Hardware Features
Low power operation
Full Power Management with individual or ganged
power control of each downstream port
On-chip Power On Reset (POR)
Internal 1.8V Voltage Regulator
Fully integrated USB termination and Pull-up/Pull-
down resistors
On Board 24MHz Crystal Driver, Resonator or
External 24/48MHz clock input
USB host/device speed indicator. Per-port 3-color
LED drivers that indicate the speed of USB host and
device connection - hi-speed (480 Mbps), full-speed
(12 Mbps), low-speed (1.5 Mbps) (48-pin QFN)
Enhanced EMI rejection and ESD protection
performance
OEM Selectable Features
Customize Vendor ID, Product ID, and Device ID
Select whether the hub is part of a compound device
(When any downstream port is permanently
hardwired to a USB peripheral device, the hub is part
of a compound device)
Flexible port mapping and disable sequence. Ports
can be disabled/reordered in any order to support
multiple product SKUs. Hub will automatically reorder
the remaining ports to match the Host controller's
numbering scheme
Programmable USB differential-pair pin location
Ease PCB layout by aligning USB signal lines directly
to connectors
Programmable USB signal drive strength. Recover
USB signal integrity due to compromised system
environment using 3-level driving strength resolution
Select the presence of a permanently hardwired USB
peripheral device on a port by port basis
Configure the delay time for filtering the over-current
sense inputs
Configure the delay time for turning on downstream
port power
Configure the polarity of downstream port power
control signals
Indicate the maximum current that the 3-port hub
consumes from the USB upstream port
Indicate the maximum current required for the hub
controller
Supports Custom String Descriptor up to 31
characters in length for:
– Product String
– Manufacturer String
– Serial Number String
Pin Selectable Options for Default Configuration
— Select Downstream Ports as Non-Removable Ports
— Select Downstream Ports as Disabled Ports
— Select Downstream Port Power Control and Over-
Current Detection on a Ganged or Individual Basis
— Select Downstream Port Power Control Polarity
— Select USB Signal Drive Strength
— Select USB Differential Pair Pin location
— Select on-chip or off-chip voltage regulator mode
Applications
LCD monitors and TVs
Multi-function USB peripherals
PC mother boards
Set-top boxes, DVD players, DVR/PVR
Printers and scanners
PC media drive bay
Portable hub boxes

Chapter 3 Pin Descriptions
3.1 PIN Descriptions
This section provides a detailed description of each signal. The signals are arranged in functional
groups according to their associated interface.
The “N” symbol in the signal name indicates that the active, or asserted, state occurs when the signal
is at a low voltage level. When “N” is not present before the signal name, the signal is asserted when
at the high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation, indicates that a signal is inactive.

UPSTREAM USB INTERFACES
USBUP_DP
USBUP_DM 31 30 43 42 IO-U USB Bus Data
These pins connect to the upstream USB bus data
signals (Host port, or upstream hub).
VBUS_DET 27 35 I/O12 Detect Upstream VBUS Power
Detects state of Upstream VBUS power. The SMSC Hub
monitors VBUS_DET to determine when to assert the
internal D+ pull-up resistor (signaling a connect event).
When designing a detachable hub, this pin must be
connected to the VBUS power pin of the USB port that
is upstream of the hub.
For self-powered applications with a permanently
attached host, this pin must be connected to 3.3V
(typically VDD33).

If this strap is enabled by package and configuration

RESET_N negation to determine the electrical
connection polarity of the downstream USB Port pins
(USB_DP and USB_DM).
Also, the active state of the LED will be determined as

If this strap is enabled by package and configuration

PRTPWR_POL n/a 38 IPU Port Power Polarity strapping
Port Power Polarity strapping determination for the
active signal polarity of the [3:1]PRTPWR pins.
While RESET_N is asserted, the logic state of this pin
will (through the use of internal combinatorial logic)
determine the active state of the [3:1]PRTPWR pins in
order to ensure that downstream port power is not
inadvertently enabled to inactive ports during a
hardware reset.
When RESET_N is negated, the logic value will be
latched internally, and will retain the active signal polarity
for the PRTPWR[3:1] pins.
‘1’ = PRTPWR[3:1]_P/N pins have an active ‘high’
polarity
‘0’ = PRTPWR[3:1]_P/N pins have an active ‘low’
polarity
Warning: Active Low port power controllers may glitch
the downstream port power when system power is first
applied. Care should be taken when designing with
active low components!
Note: If PRTPWR_POL is not an available pin on the
package, the hub will support active high
power controllers only!

Chapter 4 Configuration Options
4.1 3-Port Hub
SMSC’s USB 2.0 3-Port Hub is fully specification compliant to the Universal Serial Bus Specification
Revision 2.0 April 27, 2000 (12/7/2000 and 5/28/2002 Errata). Please reference Chapter 10 (Hub
Specification) for general details regarding Hub operation and functionality.
For performance reasons, the 3-Port Hub provides 1 Transaction Translator (TT) per port (defined as
Multi-TT configuration), divided into 4 non-periodic buffers per TT.
4.1.1 Hub Configuration Options
The SMSC Hub supports a large number of features (some are mutually exclusive), and must be
configured in order to correctly function when attached to a USB host controller. There are three
principal ways to configure the hub: SMBus, EEPROM, or by internal default settings (with or without
pin strapping option over-rides). In all cases, the configuration method will be determined by the
CFG_SEL2, CFG_SEL1 and CFG_SEL0 pins immediately after RESET_N negation.
4.1.1.1 Power Switching Polarity
The selection of active state “polarity” for the PRTPWR pins is made by a strapping option only (the
PRTPWR_POL pin).
Note: If PRTPWR_POL is not an available pin on the package, the hub will support active high power
controllers only!
4.1.2 VBus Detect
According to Section 7.2.1 of the USB 2.0 Specification, a downstream port can never provide power
to its D+ or D- pull-up resistors unless the upstream port’s VBUS is in the asserted (powered) state.
The VBUS_DET pin on the Hub monitors the state of the upstream VBUS signal and will not pull-up
the D+ resistor if VBUS is not active. If VBUS goes from an active to an inactive state (Not Powered),
Hub will remove power from the D+ pull-up resistor within 10 seconds.

4.3 EEPROM Interface
The SMSC Hub can be configured via a 2-wire (I2C) EEPROM (256x8). (Please see Table 3.1 for
specific details on how to enable configuration via an I2C EEPROM).
The Internal state-machine will (when configured for EEPROM support) read the external EEPROM for
configuration data. The hub will then “attach” to the upstream USB host.
Note: The Hub does not have the capacity to write, or “Program,” an external EEPROM. The Hub
only has the capability to read external EEPROMs. The external eeprom will be read (even if
it is blank or non-populated), and the hub will be “configured” with the values that are read.
Please see Internal Register Set (Common to EEPROM and SMBus) for a list of data fields available.
