AU6259 - USB 2.0 HUB Controller

AU6259 is a fully compliant with the USB 2.0 hub specification and is designed to work with USB host as a high-speed hub. Its built-in TT (Transaction Translator) allows system to benefit combinational performance under the unbalanced traffic condition.
AU6259-JBL supports four USB downstream ports and one upstream port in 48LQFP package. Each downstream port could be a device of high-speed, full-speed or low-speed traffic, while the upstream port supports both high-speed and full-speed traffic. For each downstream port it has individual power switch control built-in as over-current sensing control. Alcor also offers an individual power version (AU6259-JDL), with a slightly different pin-out
In addition to the application as a stand-alone hub, AU6259 is also very suitable for usage in notebook and motherboard design to provide additional USB ports. All these product advantages should be attributed to its compliance to standards, performance and low power consumption.
 

Main Features:

  • Fully compliant with USB Hub Specification version 2.0 and is also backward compatible with USB Hub specification 1.1
  • Single chip USB 2.0 hub controller.
  • Supports four bus-powered/self-powered downstream ports.
  • Supports automatic switching between bus- and self-powered modes.
  • Cost effective design using one transaction translator for all downstream ports.
  • Two-color LED controls available for each downstream port to indicate the status of each device port.
  • Extra low power consumption.
  • Built-in 15K pull-down resistors for all data lines of downstream ports.
  • Built-in USB 2.0 transceiver.
  • Supports gang mode of power management.
  • Built-in power enabling control and over current sensing control for power switch application.
  • Built-in 5V to 3.3V and 3.3V to1.8V regulator for core logic.
  • Embedded in PLL (Phase Lock Loop) circuit for 12MHz operation precision.
  • Supports external EEPROM interface for customized PID and VID.
  • Port status configurable through EEPROM input pin:
    • 2 ports. Both removable. (EEENABLE: 0, E2PSDA: 0, E2PSCL: 0)
    • 2 ports. Both non-removable. (EEENABLE: 0, E2PSDA: 0, E2PSCL: 1)
    • 3 ports. Port 1: non-removable. Port 2, 3: removable. (EEENABLE: 0, E2PSDA: 1, E2PSCL: 0)
    • Normal mode. (EEENABLE: 0, E2PSDA: 1, E2PSCL: 1)
  • Available in 48-LQFP package.
