PIC12F508/509/16F505 8/14-Pin, 8-Bit Flash MCU Data Sheet

1 PIC12F508/509/16F505 . Data Sheet 8/14-Pin, 8-Bit Flash Microcontrollers 2009 Microchip Technology Inc. DS41236E. 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.

2 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.
