... The LAN9514 hub provides over 30 programmable features, including: PortMap (also referred to as port remap) which provides flexible port mapping and disabling sequences. The downstream ports of the LAN9514 hub can be reordered or disabled in any sequence to support multiple platform designs’ with minimum effort. For any port that is disabled, the LAN9514 automatically reorders the remaining ports to match the USB host controller’ ...

... Port Power Control Using a USB Power Switch The LAN9514 has a single port power control and over-current sense signal for each downstream port. When disabling port power the driver will actively drive a ‘0’. To avoid unnecessary power dissipation, the internal pull-up resistor will be disabled at that time. When port power is enabled, the output driver is disabled and the pull-up resistor is enabled, creating an open drain output ...
Page 17
... Port Power Control Using a Poly Fuse When using theLAN9514 with a poly fuse, an external diode must be used (See disabling port power, the driver will drive a ‘0’. This procedure will have no effect since the external diode will isolate the pin from the load. When port power is enabled, the output driver is disabled and the pull-up resistor is enabled, which creates an open drain output ...
Page 18
... Many customers use a single poly fuse to power all their devices. For the ganged situation, all power control pins must be tied together.

... Note: Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal resistors to drive signals external to LAN9514. When connected to a load that must be pulled high, an external resistor must be added. PD 50uA (typical) internal pull-down. Unless otherwise noted in the pin description, internal pull-downs are always enabled ...

... Chapter 3 EEPROM Controller (EPC) LAN9514 may use an external EEPROM to store the default values for the USB descriptors and the MAC address. The EEPROM controller supports most “93C46” type EEPROMs. A total of nine address bits are used to support 256/512 byte EEPROMs. Note: A 3-wire style 2K/4K EEPROM that is organized for 256/512 x 8-bit operation must be used. ...
