2-Port SS/HS USB Hub Controller

Datasheet

PRODUCT FEATURES

General Description

Features

The SMSC USB5532B hub is a 2-port SuperSpeed/Hi-

Speed, low-power, configurable hub controller family

fully compliant with the USB 3.0 Specification. The

USB5532B supports 5 Gbps SuperSpeed (SS),

480 Mbps Hi-Speed (HS), 12 Mbps Full-Speed (FS) and

1.5 Mbps Low-Speed (LS) USB signalling for complete

coverage of all defined USB operating speeds.



USB 3.0 compliant 5 Gbps, 480 Mbps, 12 Mbps and

1.5 Mbps operation, USB pins are 5 V tolerant

—

Integrated termination and pull-up/pull-down resistors



Two downstream USB 3.0 ports

Supports battery charging of most popular battery

powered devices

—

USB-IF Battery Charging rev. 1.2 support (DCP & CDP)

Apple Portable product charger emulation

Blackberry charger emulation

Chinese YD/T 1591-2006 charger emulation

Chinese YD/T 1591-2009 charger emulation

Supports additional portable devices

The USB5532B supports legacy USB speeds through its

USB 2.0 hub controller. The new SuperSpeed hub

controller operates in parallel with the USB 2.0

controller, so the 5 Gbps SuperSpeed data transfers are

not affected by the slower USB 2.0 traffic.



Emulates portable/handheld native wall chargers

—

Charging profiles emulate a handheld device’s wall

charger to enable fast charging (minutes vs. hours)

The USB5532B supports battery charging on a per port

basis. On battery charging enabled ports, the devices

provide automatic USB data line handshaking. The

handshaking supports USB 1.2 Charging Downstream

Port (CDP), Dedicated Charging Port (DCP) and legacy

devices.



Enables charging from a mobile platform that is off

Support tablets’ high current requirements

Optimized for low-power operation and low thermal

dissipation

Vendor Specific Messaging (VSM) support for

firmware upload over USB



The USB5532B is configured for operation through

internal default settings, where custom configurations

are supported through an on-chip OTP ROM, an

external SPI ROM, or SMBus.



Configuration via OTP ROM, SPI ROM, or SMBus

On-chip 8051 µC manages VBUS, and other hub

signals



8 K RAM, 32 K ROM

One Time programmable (OTP) ROM: 8 kbit

—

Includes on-chip charge pump



Single 25 MHz XTAL or clock input for all on-chip PLL

and clocking requirements



Supports JTAG boundary scan

PHYBoost (USB 2.0)

—

Selectable drive strength for improved signal integrity



VariSense (USB 2.0)

—

controls the receiver sensitivity enabling four

programmable levels of USB signal receive sensitivity



IETF RFC 4122 compliant 128-bit UUID

Software Features



Compatible with Microsoft Windows 7, Vista, XP,

Mac OSX10.4+, and Linux Hub Drivers
