The TUSB8040 is USB 3.0 compliant hub available in an 80-pin QFP package. The device is designed for operation over the commercial temperature range of 0°C to 70°C.

The TUSB8040 provides simultaneous SuperSpeed and high-speed/full-speed connections on the upstream port and provides SuperSpeed, 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 or full-speed/low-speed connections, SuperSpeed connectivity is disabled on the downstream ports. When the upstream port is connected to an electrical environment that only supports full-speed/lowspeed connections, SuperSpeed and high-speed connectivity are disabled on the downstream ports.

The TUSB8040 supports up to four downstream ports. It may be configured to report one to four downstream ports by pin selection or an attached EEPROM or SMBus controller. The configuration options provide the ability to scale the device by application.
