Introduction
U2H4+IDE01 is an USB 2.0 four-port HUB with one USB to IDE (ATA/ATAPI) bridge. U2H4+IDE01 provides three downstream ports USB 2.0 HUB and one IDE (ATA/ATAPI) connector. It is ideally suited for tailgate interface applications for removable-media drives CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM, tape drive, and hard disk drive.
It also allows IDE drives (Master and Slave) to be connected to USB 2.0 serial bus in a plug-and-play fashion. Both ATA and ATAPI devices are supported using the same firmware.

Technical Specifications

U2H4+IDE01 combines two key components:
 1). Cypress CY7C65640A TetraHubTM: Four ports USB 2.0 High Speed Hub
2). CY7C68300B: USB 2.0 to IDE (ATA/ATAPI) Bridge Board

1). Cypress CY7C65640A TetraHubTM: Four ports USB 2.0 High Speed Hub

The Tetra architecture provides four downstream USB ports, with a Transaction Translator (TT) for each port, making it the highest performance hub possible.

The U2H4+IDE01 works backward compatible either when any one of downstream ports are connected to an USB 1.1 compliant device, or when the upstream port is connected to a USB 1.1 compliant host.

  • Compliant with USB 2.0(Data Rate 1.5/12/480Mbps)
    4 downstream ports
    • Two downstream ports (USB1&2) are Intel block berg-strip header (2x5/9 pin).
    • One downstream port (USB4) is JST 5pin compatible connector.
    • One downstream internal port for USB 2.0 to IDE Bridge Board
  • Multiple transaction translators
    • One per downstream port for maximum performance
  • All downstream facing ports can handle high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) transaction.
  • Supports self-powered mode only
  • Supports Over-current detection and Individual / Gang power control
  • Supports configurable vendor ID and product ID with external Serial ROM
  • Supports non-removable attribution on individual port

2). USB 2.0 to IDE (ATA) Bridge:

  • USB Bus Transfer Rate: High Speed (480 Mbit) And Full Speed (12 Mbit)
  • USB Bus Power: Self Powered Mode Operation
  • USB 2.0 to ATA Native Bridge Controller: CY7C68300B

    • PIO Mode 0, 3, 4
    • Ultra DMA Mode 2, 4
    • Ultra DMA Mode 0 ~ 4
    • Supports 48-bit addressing for large hard drives (>128GB).
  • IDE (ATA/ATAPI) Interface: Male IDC 2X20 Connector
  • The IDE (ATA/ATAPI) port supports multi-LUN function for attaching two (Master and Slave) IDE devices.
  • Both ATA and ATAPI devices are supported using the same firmware.
  • Power indicator LED and HDD Access LED
Physical Dimensions
  • 8.90cm (W) x 1.95cm (H) x 5.85cm(D)
  • Form Factor
    • SCSI I 50pin Low Density Centronics Connector
