General Description
The SMSC USB5534 hub is a 4-port, low-power,
configurable Hub Controller fully compliant with the USB
3.0 Specification. The USB5534 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.
The USB5534 supports the 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.
The USB5534 is configured for operation through
internal default settings, where custom configurations
are supported through an on-chip OTP ROM or an
external SPI ROM.
All LED and port control signal pins are under firmware
control in order to allow for maximum operational
flexibility; those pins can also be configured as GPIOs.
