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 publications 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.
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., DS30000000A is version A of document DS30000000).
Errata
An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for cur-
rent 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 number) you are
using.

INTRODUCTION
The Microchip 2-Port Hub is fully compliant with the USB 2.0 Specification and will attach to a USB host as a Full-Speed
Hub or as a Full-/High-Speed Hub. The 2-Port Hub supports Low-Speed, Full-Speed, and High-Speed (if operating as
a High-Speed Hub) downstream devices on all of the enabled downstream ports.
The Hub works with an external USB power distribution switch device to control V
BUS
switching to downstream ports,
and to limit current and sense over-current conditions.
All required resistors on the USB ports are integrated into the Hub. This includes all series termination resistors on D+
and D– pins and all required pull-down and pull-up resistors on D+ and D– pins. The over-current sense inputs for the
downstream facing ports have internal pull-up resistors.
Throughout this document the upstream facing port of the hub will be referred to as the upstream port, and the down-
stream facing ports will be called the downstream ports.
1.1
OEM Selectable Features
A default configuration is available in the USB2502 following a reset. This configuration may be sufficient for some appli-
cations. Strapping option pins make it possible to modify a limited sub-set of the configuration options.
The USB2502 may also be configured by an external EEPROM or a microcontroller. When using the microcontroller
interface, the Hub appears as an SMBus slave device. If the Hub is pin-strapped for external EEPROM configuration
but no external EEPROM is present, then a value of ‘0’ will be written to all configuration data bit fields (the hub will
attach to the host with all ‘0’ values).
The 2-Port Hub supports several OEM selectable features:
• Operation as a Self-Powered USB Hub or as a Bus-Powered USB Hub.
• Operation as a Dynamic-Powered Hub (Hub operates as a Bus-Powered device if a local power source is not
available and switches to Self-Powered operation when a local power source is available).
• Optional OEM configuration via I
2
C EEPROM or via the industry standard SMBus interface from an external
SMBus Host.
• Compound device support (port is permanently hardwired to a downstream USB peripheral device).
• Hardware strapping options enable configuration of the following features.
- Non-Removable Ports
- Port Power Polarity (active high or active low logic)
