Resumen del producto

The TUSB2077APT is a 7-port USB Hub with optional serial EEPROM interface. 3.3V CMOS device that provides up to seven downstream ports in compliance with the USB 2.0 specification. Because this device is implemented with a digital state machine instead of a microcontroller, no software programming is required. Fully-compliant USB transceivers are integrated into the ASIC for all upstream and downstream ports. The downstream ports support both full-speed and low-speed devices by automatically setting the slew rate according to the speed of the device attached to the ports. The configuration of the BUSPWR terminal selects either the bus-powered or self-powered mode. The introduction of the DP0 pull-up resistor disable terminal, DP0PUR, makes it much easier to implement an onboard bus/self-power dynamic-switching circuitry. The three LED indicator control output terminals also enable the implementation of visualized status monitoring of the hub and its downstream ports.
  • Fully compliant with USB specification as a full-speed hub
  • Integrated USB transceivers
  • 3.3V Low-power ASIC logic
  • Self-powered mode supporting 7 downstream ports, bus-powered mode supporting 4 downstream ports
  • All downstream ports support full-speed and low-speed operations
  • Power switching and overcurrent reporting is provided ganged or per port
  • Supports suspend and resume operations
  • Suspend status terminal available for external logic power down
  • Supports custom vendor ID and product ID with external serial EEPROM
  • 3-state EEPROM interface allows EEPROM sharing
  • Push-pull outputs for PWRON eliminate need for external pull-up resistors
  • Noise filtering on OVRCUR provides immunity to voltage spikes
  • Supports 6MHz operation through a crystal input or a 48MHz input clock
  • New functional terminals introduced to reduce board material cost
  • No special driver requirements, works seamlessly with any operating system with USB stack support
  • Green product and no Sb/Br
