Introduction
The TUSB8040A is a four-port USB 3.0 compliant hub. The TUSB8020A is a two-port USB 3.0 compliant
hub. The two devices are pin compatible and available in a 100-pin QFN package or 80-pin QFP package.
The device is designed for operation over the commercial temperature range of 0°C to 70°C.
The TUSB80x0A provides simultaneous SuperSpeed USB and high-speed/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 or full-speed/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/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 (RKM version only) or by an attached EEPROM or SMBus controller.
The configuration options provide the ability to scale the device by application. The TUSB8020A supports
up to two downstream ports and provides configuration options by pin selection (RKM version only) and
EEPROM/SMBus as well.
A typical system view of the TUSB8040A is shown in Figure 1-1.
