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 QS-9000 quality system 
certification for its worldwide headquarters, 
design and wafer fabrication facilities in 
Chandler and Tempe, Arizona in July 1999 
and Mountain View, California in March 2002. 
The Company’s quality system processes and 
procedures are QS-9000 compliant for its

systems is ISO 9001 certified.
