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and may be superseded by updates.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.

INCLUDING BUT NOT LIMITED TO ITS CONDITION,

BOARD USER’S GUIDE

Chapter 1. Product Overview

1.1 OVERVIEW

This chapter provides an overview of the MCP2515 PICtail Plus Daughter Board and
covers the following topics:

•Overview

• What is the MCP2515 PICtail Plus Daughter Board?

• What the MCP2515 PICtail Plus Daughter Board kit includes.

1.2 WHAT IS THE MCP2515 PICTAIL PLUS DAUGHTER BOARD?

The MCP2515 PICtail Plus Daughter Board is a simple Controller Area Network (CAN)
board designed to be used with boards containing the PICtail Plus connector. The
board also has the PICkit Serial connector for interfacing to the PICkit Serial Analyzer
tool.

The CAN node consists of the MCP2515 Stand-Alone CAN controller and MCP2551
CAN transceiver. The PICkit Plus and PICkit Serial connectors allow the board to be
interfaced to a variety of PICmicros so that the user can deve lo p a CA N no de.

The board also contains headers or test points for most of the MCP2515 pins to allow
the external functions to be monitored /e va l ua te d .
