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.

4 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 QS-9000 quality system certification for its worldwide headquarters, design and wafer fabrication facilities in Chandler and Tempe, Arizona in July 1999 and Mountain View, California in March 2002.

5 The Company s quality system processes and procedures are QS-9000 compliant for its PICmicro 8-bit MCUs, KEELOQ code hopping devices, Serial EEPROMs, microperipherals, non-volatile memory and analog products. In addition, Microchip s quality system for the design and manufacture of development systems is ISO 9001 certified. 2003 Microchip Technology 1 PIC16F87 XADevices Included in this Data Sheet :High-Performance RISC CPU: Only 35 single-word instructions to learn All single-cycle instructions except for program branches, which are two-cycle Operating speed: DC 20 MHz clock inputDC 200 ns instruction cycle Up to 8K x 14 words of flash Program Memory, Up to 368 x 8 bytes of Data Memory (RAM), Up to 256 x 8 bytes of EEPROM Data Memory Pinout compatible to other 28-pin or 40/44-pin PIC16 CXXX and PIC16 FXXX microcontrollersPeripheral Features: Timer0: 8-bit timer/counter with 8-bit prescaler Timer1.
