Microchip USB5532B 2/3/4/7-Port SuperSpeed/Hi-Speed USB Hub Controller

Microchip USB553xB 2/3/4/7-Port
SuperSpeed/Hi-Speed USB Hub Controller

Microchip's USB553xB Hi-Speed USB 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 supports 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 the 5Gbps SuperSpeed data transfers are not affected by the slower USB 2.0 traffic.
