The TUSB8040AEVM board is a free standing reference design for TUSB8040A, a four port SuperSpeed USB (USB 3.0) hub 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 evaluation module will work with USB 2.0 hosts systems as a USB 2.0 hub. No software is required to enable the device. The board will work with any operating system that has USB hub class support built in.
- Supports operation as a USB 3.0 or USB 2.0
- Upstream port supports SuperSpeed USB high speed and full speed connections
- Test via on board jumpers/LEDs
- Supports on board and in system EEPROM programming Via the USB 2.0 upstream Port
- Supports per port or ganged power switching and over current notification inputs
- Optional serial EEPROM or SMBus slave interface for custom configurations
- Provides 128bit universally unique identifier
- Optionally supports USB 2.0 compliant port indicator LEDs
- Single clock input, 24MHz crystal or oscillator
- No special driver requirements
