Texas Instruments (TUSB2036VF) USB Interface, USB Hub Controller

Product Overview The TUSB2036VF is a 3-port Hub that provides up to three 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 firmware 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 pin selects either the bus-powered or the self-powered mode. The introduction of the DP0 pull-up resistor disable pin, DP0PUR, makes it much easier to implement an onboard bus/self-power dynamic-switching circuitry. With the new function pin, the end-equipment vendor can reduce the total board cost while adding additional product value. The TUSB2036 supports both bus-powered and self-powered modes. Integrated USB transceivers 3.3V Low power ASIC logic One upstream port and 3 programmable downstream ports Two power source modes (self-powered mode, bus-powered mode) All downstream ports support full-speed and low-speed operations Power switching and over-current reporting is provided ganged or per port Supports suspend and resume operations Suspend status pin available for external logic power down 3-state EEPROM interface allows EEPROM sharing Push-pull outputs for PWRON eliminate the 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 No special driver requirements Green product and no Sb/Br Applications Computers & Computer Peripherals, Consumer Electronics Product Information USB IC Type: USB Hub Controller USB Standard: USB 2.0 Supply Voltage Min: 3V Supply Voltage Max: 3.6V Interface Case Style: LQFP No. of Pins: 32Pins Data Rate: 12Mbps No. of Ports: 3 Port Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - MSL: MSL 3 - 168 hours
