Printed on recycled 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.
4 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 ourproducts. Attempts to break Microchip s code protection feature may be a violation of the Digital Millennium Copyright Act. If such actsallow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that received ISO/TS-16949:2002 quality system certification for its worldwide headquarters, design and wafer fabrication facilities in Chandler and Tempe, Arizona and Mountain View, California in October 2003. The Company s quality system processes and procedures are for its PICmicro 8-bit MCUs, KEELOQ code hopping devices, Serial EEPROMs, microperipherals, nonvolatile memory and analog products.
5 In addition, Microchip s quality system for the design and manufacture of development systems is ISO 9001:2000 certified. 2005 Microchip Technology 1 PIC16F685/687/689/690 High-Performance RISC CPU: Only 35 instructions to learn:- All single-cycle instructions except branches Operating speed:- DC 20 MHz oscillator/clock input- DC 200 ns instruction cycle Interrupt capability 8-level deep hardware stack Direct, Indirect and Relative Addressing modesSpecial Microcontroller Features: Precision Internal Oscillator:- Factory calibrated to 1%- Software selectable frequency range of 8 MHz to 32 kHz- Software tunable- Two-Speed Start-up mode- Crystal fail detect for critical applications- Clock mode switching during operation for power savings Power-saving Sleep mode Wide operating voltage range ( ) Industrial and Extended Temperature range Power-on Reset (POR) Power-up Timer (PWRTE) and Oscillator Start-up Timer (OST) Brown-out Reset (BOR) with software control option Enhanced low-current Watchdog Timer (WDT) with on-chip oscillator (software selectable nominal 268 seconds with full prescaler) with software enable Multiplexed Master Clear/Input pin Programmable code protection High Endurance Flash/EEPROM cell.
