CERTIFIED BY DNV

== ISO/TS 16949 ==

• 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.

USER’S GUIDE

Chapter 1. MCP251XFD CAN FD Motherboard

1.1 INTRODUCTION

The MCP251XFD CAN FD Motherboard provides a simple, low-cost board to evaluate the MCP2517FD family of devices. The board features one mikroBUS™ socket to accommodate the MCP2517FD click Board.

The MCP251XFD CAN FD Motherboard together with the MCP2517FD click Board can be used to implement a CAN FD node.

The MCP251XFD CAN FD Motherboard contains a PIC32MX470F512H microcontroller with a Service Provider Interface (SPI) peripheral. The microcontroller controls the MCP2517F D via the SPI interfac e.

A firmware Application Program Interface (API) is available for rapid application development, which is written in C programming language for MPLAB Harmony Integrated Software Framework. It can be easily ported to other microcontrollers.

1.2 RECOMMENDED ITEMS TO IMPLEMENT A CAN FD NODE

In order to implement a CAN FD node using the MCP2517FD, the following items are recommended:

• MCP251XFD CAN FD Motherboard (ADM005 76)

• MCP2517FD click Board (NOT included)

• Mini-USB Cable (NOT included)

1.3 KIT CONTENTS

The MCP251XFD CAN FD Motherboard kit includes:

• MCP251XFD CAN FD Motherboard (ADM005 76)

• Information Sheet
