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. 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. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

Chapter 1. Introduction to the XLP 8-Bit Board
1.1 INTRODUCTION
Thank you for purchasing Microchip Technology’s XLP 8-Bit Development Board.
The board provides a low-cost, highly configurable development system for Microchip’s
new line of 64 and 80-pin Extreme Low-Power (XLP) microcontrollers, including the
PIC16(L)F1947 and PIC18F87K22 families.
The XLP 8-bit board permits users to explore and evaluate extreme low-power
features, and learn low-power software and hardware techniques. Various headers are
available to measure the power consumption of both the microcontroller and
development board. It is flexible, supporting five different power sources over a wide
voltage range. It is highly configurable, equipped with a variety of common peripheral
components that can be selectively enabled. Finally, it is expandable through its
modular interface, providing for the addition of advanced interfaces and connectivity
methods.
As provided, the XLP 8-Bit Development Board functions as a demonstration platform
on initial power-up. The included demonstration software takes a temperature
measurement, datalogs information to the serial data EEPROM, and displays
information to the on-board LCD. Additional software is provided to demonstrate
low-power techniques and IC interface routines.
