Summary
Microchip's USB553xB hub controllers are 2/3/4/7-port, SuperSpeed (SS)/Hi-Speed (HS), low-power, configurable and fully-compliant with the USB 3.0 specification. The USB553xB also support Full Speed (FS) and Low Speed (LS) USB signaling, offering complete coverage of all defined USB operating speeds. The new SuperSpeed hub controller (available on 4 of the 7 ports for the USB5537B) operates in parallel with the USB 2.0 controller, so 5Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.
