Texas Instruments (TUSB2036VF) USB Interface, USB Hub Controller

Product OverviewThe TUSB2036VF is a 3-port Hub that provides up to three downstream ports incompliance with the USB 2.0 specification. Because this device is implementedwith a digital state machine instead of a microcontroller, no firmwareprogramming is required. Fully-compliant USB transceivers are integrated intothe ASIC for all upstream and downstream ports. The downstream ports supportboth full-speed and low-speed devices by automatically setting the slew rateaccording to the speed of the device attached to the ports. The configuration ofthe BUSPWR pin selects either the bus-powered or the self-powered mode. Theintroduction of the DP0 pull-up resistor disable pin, DP0PUR, makes it mucheasier to implement an onboard bus/self-power dynamic-switching circuitry. Withthe new function pin, the end-equipment vendor can reduce the total board costwhile adding additional product value. The TUSB2036 supports both bus-poweredand self-powered modes.Integrated USB transceivers3.3V Low power ASIC logicOne upstream port and 3 programmable downstream portsTwo power source modes (self-powered mode, bus-powered mode)All downstream ports support full-speed and low-speed operationsPower switching and over-current reporting is provided ganged or per portSupports suspend and resume operationsSuspend status pin available for external logic power down3-state EEPROM interface allows EEPROM sharingPush-pull outputs for PWRON eliminate the need for external pull-up resistorsNoise filtering on OVRCUR provides immunity to voltage spikesSupports 6MHz operation through a crystal input or a 48MHz input clockNo special driver requirementsGreen product and no Sb/BrApplicationsComputers & Computer Peripherals, Consumer ElectronicsProduct InformationUSB IC Type: USB Hub ControllerUSB Standard: USB 2.0Supply Voltage Min: 3VSupply Voltage Max: 3.6VInterface Case Style: LQFPNo. of Pins: 32PinsData Rate: 12MbpsNo. of Ports: 3 PortOperating Temperature Min: 0°COperating Temperature Max: 70°CProduct Range: -MSL: MSL 3 - 168 hours
