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.

3 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 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.

4 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. In addition, Microchip s quality system for the design and manufacture of development systems is ISO 9001:2000 certified. 2005 Microchip Technology 1 PIC16F87/88 Low-Power Features: Power-Managed modes:- Primary Run: RC oscillator, 76 A, 1 MHz, 2V- RC_RUN: 7 A, kHz, 2V- SEC_RUN: 9 A, 32 kHz, 2V- Sleep: A, 2V Timer1 Oscillator: A, 32 kHz, 2V Watchdog Timer: A, 2V Two-Speed Oscillator Start-upOscillators: Three Crystal modes:- LP, XT, HS: up to 20 MHz Two External RC modes One External Clock mode:- ECIO: up to 20 MHz Internal oscillator block:- 8 user selectable frequencies: 31 kHz, 125 kHz, 250 kHz, 500 kHz, 1 MHz, 2 MHz, 4 MHz, 8 MHzPeripheral Features: Capture, Compare, PWM (CCP) module:- Capture is 16-bit, max.
