PL27A1   Super-Speed USB Host to Host Controller

The PL27A1 is a single-chip SuperSpeed USB 3.0 Host-to-Host bridge controller specially designed for USB host to host data transfer. SuperSpeed USB has data transfer bandwidth of up to 5Gbps offering 10X performance increase over Hi-Speed USB 2.0 (480Mbps). SuperSpeed USB is backward compatible and interoperates with all USB3.0/USB2.0/USB1.1 hosts, devices, and hubs. 

The PL27A1 chip offers external firmware customization for various data transfer mode protocols:

  • WINUSB(Transfer cable)
  • CDC/ACM (USB Serial Device)
  • RNDIS (Network Cable)

  • SuperSpeed USB 3.0 Host-to-Host Bridge Controller
  • USB 3.0 and USB 2.0 specification compliant
  • SuperSpeed (5Gbps), Hi-Speed (480Mbps), and Full-Speed (12Mbps)
  • Transfer data between two USB Hosts (up to SuperSpeed USB 3.0)
  • Supports firmware customization for various transfer protocol modes:
    • 27A1 mode- WINUSB(Easy Transfer cable)
    • 27A3 mode – CDC/ACM (USB Serial Device)
    • 27A5 mode – RNDIS (Network Cable)
    • 27A7 mode-WINUSB (Custom USB Transfer Cable)
  • WINUSB and CDC/ACM drivers are built in Windows, Mac OS and Linux(for ACM), An inf file is needed for driver installation on Win7 and 8.1.  RNDIS driver is built in Windows and Linux.
  • Easy Transfer Cable fully supports Microsoft Windows Easy Transfer built-in software in Windows Vista, Windows 7, and Windows 8.
