4포트 SuperSpeed USB 5Gbps USB 3.0 허브
TUSB8040A1
- 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
- Supports per port or ganged power switching and overcurrent notification inputs
- Provides the following status outputs:
- High-speed upstream connection
- High-speed upstream port suspended
- SuperSpeed USB upstream connection
- SuperSpeed USB upstream port suspended
- Optional serial EEPROM or SMBus target interface for custom configurations:
- VID or PID
- Manufacturer and product strings
- Serial number
- Using pin selection or EEPROM and SMBus target interface, each downstream port can be independently:
- Enabled or disabled
- Marked as removable or permanently attached (for compound applications)
- Have battery charging enabled or disabled
- Provides 128-bit universally unique identifier (UUID)
- Optionally supports USB 2.0 compliant port indicator LEDs
- Configurable SMBus address to support multiple devices on the same SMBus segment
- Supports onboard and in-system EEPROM programming through the USB 2.0 upstream port
- Single clock input, 24-MHz crystal or oscillator
- No special driver requirements; works seamlessly with any operating system with USB stack support
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.
