USB5537B

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.

Features
  • Two, three, or four downstream USB 3.0 ports (which also support USB 2.0)
  • Three additional USB 2.0 ports for non-removable devices (USB5537B only)
  • Designed for low-power operation and low thermal dissipation
  • On-chip 8051 µC manages GPIOs, VBUS, and other hub signals
  • Configuration via on-chip programmable ROM, SPI ROM or SMBus
  • Manufacturing line and field update capabilities
  • Power management capability on GPIO/LED pins
  • One-Time Programmable (OTP) ROM (8 kbit), including on-chip charge pump
  • IETF RFC 4122 compliant 128-bit UUID
  • Compatible with Microsoft® Windows® 8 and other major OS’s
  • Microchip’s TrueSpeed LEDs (configuration dependent) Multi-color LED scheme shows port capability and speed
  • Multi-color LED scheme shows port capability and speed
  • Embedded 8051 microcontroller for hub configuration
  • 64 or 72-pin, low-cost QFN packages enable 2-layer PCB design
  • Expansion Hubs
  • Docking Stations
  • LCD Monitors
  • HDTVs
