The TUSB8040A is a four-port USB 3.0 compliant hub and is available in a 100-pin QFN package. The
device is designed for operation over the commercial temperature range of 0°C to 70°C.
The TUSB8040A 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 TUSB8040A supports up to four downstream ports. It 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.
