Product Description

The TUSB2077APTR is a 7-port Full-Speed USB 2.0 Hub with optional serial EEPROM Interface. 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 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 pins also enable the implementation of visualized status monitoring of the hub and its downstream ports.
Integrated USB transceiver
3.3V Low-power ASIC logic
Two power source modes
Self-powered mode supporting seven downstream ports
Bus-powered mode supporting four 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 pin available for external logic Power Down
Supports custom vendor ID and product ID With external serial EEPROM
3-state EEPROM interface allows EEPROM sharing
Noise filtering on OVRCUR provides immunity to voltage spikes
Supports 6MHz operation through a crystal input or a 48MHz input clock
Green product and no Sb/Br
Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
