PRODUCT FEATURES

General Description
The SMSC USB251x hub is a family of low-power, OEM
configurable, MTT (multi transaction translator)
controller IC products for embedded USB solutions. The
"x" in the part number indicates the number of
downstream ports available. The SMSC hub supports
low-speed, full-speed, and hi-speed (if operating as a hi-
speed hub) downstream devices on all of the enabled
downstream ports.

    Chapter 6 LED Usage Description LED Functionality USB2513 and USB2514 (48-pin QFN only) and USB2517/17i SMSC hubs support two different (mutually exclusive) LED modes. The ‘x’ represents the number of downstream ports. The USB mode provides up to 14 LED’s that conform to the USB 2.0 specification functional requirements for Green and Amber LED’s.
  • Page 30 LED circuit will be implemented. The circuit should be replicated for each of the x LED pins on the SMSC hub. In this circuit, when the LED pin is driven to a logic low state, the Green LED will light up. When the LED pin is driven to a Logic High state the Red LED will light up.

  • Page 31: Chapter 7 Battery Charging Support

    USB251xB hub can be configured to support battery charging. The SMSC hub provides support for battery charging devices on a per port basis in compliance with the USB Battery Charging specification, version 1.1. The hub can be configured to individually enable each downstream port for battery charging support either via pin strapping as illustrated in or by setting the corresponding configuration bits via EEPROM or SMBus.
