PIC16F7X Data Sheet

1 M. PIC16F7X . Data Sheet 28/40-pin, 8-bit CMOS FLASH. Microcontrollers 2002 Microchip Technology Inc. DS30325B. Note the following details of the code protection feature on PICmicro MCUs. The PICmicro family meets the specifications contained in the Microchip Data Sheet . Microchip believes that its family of PICmicro microcontrollers is one of the most secure products 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 knowl- edge, require using the PICmicro microcontroller in a manner outside the operating specifications contained in the data Sheet . The person doing so may be engaged in theft of intellectual property.

2 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 product. If you have any further questions about this matter, please contact the local sales office nearest to you. Information contained in this publication regarding device Trademarks applications and the like is intended through suggestion only and may be superseded by updates. It is your responsibility to The Microchip name and logo, the Microchip logo, FilterLab, ensure that your application meets with your specifications.
