  • USB 3.0 compliant hub, TID #330000037
    • Upstream port supports SuperSpeed USB, high-speed and full-speed connections
    • Supports four downstream ports
    • Each of the four downstream ports support SuperSpeed USB, high-speed, full-speed, or low-speed connections
  • USB 2.0 hub features
    • Multiple transaction translator (MTT) hub: four transaction translators, one per port
    • Four asynchronous endpoint buffers per transaction translator (TT) for better throughput than the USB-required minimum of two buffers per TT
  • Supports battery charging applications
    • Battery charging 1.2 charging downstream port (CDP) when upstream port is connected
    • Battery charging 1.2 and Chinese Telecommunications Industry Standard YD/T 1591-2009 dedicated charging port (DCP) when upstream port is disconnected
  • Supports operation as a USB 3.0 or USB 2.0 compound device

The TUSB8040A1 is a four-port USB 3.0 compliant hub and is available in a 100-pin WQFN package. The device is designed for operation over the commercial temperature range of 0°C to 70°C.

The TUSB8040A1 provides simultaneous SuperSpeed USB and high-speed or full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high-speed, full-speed, or low-speed connections, SuperSpeed USB connectivity is disabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed or low-speed connections, SuperSpeed USB and high-speed connectivity are disabled on the downstream ports.

The TUSB8040A1 supports up to four downstream ports. The device may be configured to report one to four downstream ports by pin selection or by an attached EEPROM or SMBus controller. The configuration options provide the ability to scale the device by application.
