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

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.
