TO OUR VALUED CUSTOMERS
It is our intention to provide our valued customers with the best documentation possible to ensure successful use of
your Microchip products. To this end, we will continue to improve our publications to better suit your needs. Our pub-
lications will be refined and enhanced as new volumes and updates are introduced.
If you have any questions or comments regarding this publication, please contact the Marketing Communications
Department via E-mail at
docerrors@microchip.com
or fax the
Reader Response Form
in the back of this data
sheet to (480) 792-4150. We welcome your feedback.
Most Current Data Sheet
To obtain the most up-to-date version of this data sheet, please register at our Worldwide Web site at:
http://www.microchip.com
You can determine the version of a data sheet by examining its literature number found on the bottom outside corner
of any page. The last character of the literature number is the version number, (e.g., DS30000A is version A of doc-
ument DS30000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may
exist for current devices. As device/documentation issues become known to us, we will publish an errata sheet. The
errata will specify the revision of silicon and revision of document to which it applies.
To determine if an errata sheet exists for a particular device, please check with one of the following:
• Microchip’s Worldwide Web site;
http://www.microchip.com
• Your local Microchip sales office (see last page)
When contacting a sales office, please specify which device, revision of silicon and data sheet (include literature num-
ber) you are using.

The Hub Feature Controller, sometimes called a Hub Controller for short is the internal
processor used to enable the unique features of the USB Controller Hub. This is not to
be confused with the USB Hub Controller that is used to communicate the hub status
back to the Host during a USB session.

Description
Input.
Input with Schmitt trigger.
Output buffer with 12 mA sink and 12 mA source.
Open-drain output with 12 mA sink
50 μA (typical) internal pull-up. Unless otherwise noted in the pin description, internal pull-
ups are always enabled.
Internal pull-up resistors prevent unconnected inputs from floating. Do not rely on internal
resistors to drive signals external to the device. When connected to a load that must be
pulled high, an external resistor must be added.
PD
50 μA (typical) internal pull-down. Unless otherwise noted in the pin description, internal
pull-downs are always enabled.
Internal pull-down resistors prevent unconnected inputs from floating. Do not rely on
internal resistors to drive signals external to the device. When connected to a load that
must be pulled low, an external resistor must be added.
