Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the

intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data

Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not

mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our

products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts

allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Microchip received ISO/TS-16949:2002 certification for its worldwide

headquarters, design and wafer fabrication facilities in Chandler and

NOTICE TO CUSTOMERS

All documentation becomes dated and this manual is no exception. Microchip tools and

documentation are constantly evolving to meet customer needs, so some actual dialogs

and/or tool descriptions may differ from those in this document. Please refer to our web site

(www.microchip.com) to obtain the latest documentation available.

Documents are identified with a “DS” number. This number is located on the bottom of each

page, in front of the page number. The numbering convention for the DS number is

“DSXXXXXA”, where “XXXXX” is the document number and “A” is the revision level of the

document.

RECOMMENDED READING

This user’s guide describes how to use the PIC18F46J50 Full-Speed USB Demonstra-

tion Board. The following Microchip documents are recommended as supplemental

references:

•“PIC18F46J50 Family Data Sheet” (DS39931)

• MCHPFSUSB Framework’s release notes and other documentation

Microchip provides a variety of USB related application notes, firmware, drivers, PC

application source code and other resources to assist application developers. Many of

the USB related firmware files, and PC application source code projects and documen-

tation are in the earlier referenced MCHPFSUSB Framework on the CD-ROM disc that

comes with the board. The latest version of this package and the other resources can

be downloaded at the Microchip USB design center:

http://www.microchip.com/usb/

Schematics and other support materials for the PIC18 Explorer Demonstration Board

can be obtained at:

http://www.microchip.com/pic18explorer

Schematics and other support materials for the HPC Explorer Demonstration Board

can be obtained at:

http://www.microchip.com/HPCExplorer

The official USB 2.0 specifications also could be helpful. These materials can be

obtained from the USB Implementer’s Forum:

http://www.usb.org

Chapters 5, 8 and 9 of the USB 2.0 specifications are particularly important for applica-

tion developers making USB peripheral devices. These chapters discuss important

USB protocol fundamentals and the necessary device requests that must be supported

to enable successful USB enumeration.

If considering use of the PIC18F46J50 Full-Speed USB Demonstration Board with one

of the boards discussed in Chapter 2. “Board Hardware”, the following Microchip

documents are recommended:

•PICDEM™ PIC18 Explorer Demonstration Board User’s Guide (DS51721)

•PICDEM™ HPC Explorer Board Info Sheet (DS51540)
