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.

LAN950X FAMILY DIFFERENCES OVERVIEW

The Microchip LAN950x is a family of high performance Hi-Speed USB 2.0 to 10/100 Ethernet controllers. The “x” in the

part number is a generic term referring to the entire family, which includes the following devices:

•

LAN9500

LAN9500i

LAN9500A

LAN9500Ai

Device specific features that do no pertain to the entire LAN950x family are called out independently throughout this

document.
