Microchip Devices Code Protection Feature

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.
