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/LIBUSB (Easy Transfer Cable)
  • CDC/ACM (USB Serial Device)
  • RNDIS (Network Cable)
  • CDC/ACM and RNDIS

  • 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/LIBUSB (Easy Transfer Cable)
    • 27A3 mode – CDC/ACM (USB Serial Device)
    • 27A5 mode – RNDIS (Network Cable)
    • 27A7 mode – CDC/ACM and RNDIS
  • WINUSB, CDC/ACM, and RNDIS drivers are all built inside Windows, Linux, and Mac.
  • Easy Transfer Cable fully supports Microsoft Windows Easy Transfer built-in software in Windows Vista, Windows 7, and Windows 8.

  • Application programs can be stored in external SPI Flash. This SPI Flash is enumerated by USB Mass Storage and will appear as a read-only disk drive.
  • 8-bit high-performance 1T 8032 MCU
  • Two USB device PHYs
  • USB endpoint 0 for control endpoint with dedicated 512 bytes buffer for each USB side
  • Highly configurable endpoint structure. Each endpoint can be configured as interrupt, bulk, and isochronous endpoint.
  • Pass Through Channel FIFO architecture utilize full USB bandwidth for data transfer
  • One SPI Flash Controller for external SPI Serial Flash Memory
  • Supports DMA feature between external SPI flash and internal FIFO
  • Supports multi-vendor SPI Serial Flash Memory
  • 3.3V Digital I/O Pad
  • 1.2V power supply for core
  • Built-in 5V to 3V linear low-dropout regulator
  • Embedded power-on reset (POR)
  • 30MHz crystal oscillator (shared by both USB PHYs)
  • Supports external SPI Flash to customize USB vendor/product ID
  • Supports LED indicator for connection and transfer status
  • Bus powered from either USB port
  • PKG : QFN64 packaging
