Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification cont ained 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 t oday, when used in the
intended manner and under normal conditions.
• The re are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our

• 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 c onstantly evolving. We a t Microc hip are co m mitted to continuously improving the code prot ect ion featur es of our
products. Attempts to break Microchip’ s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
