Introduction

Purpose

� This training course provides an overview of the Renesas microcontrollers (MCUs) that provide a CAN peripheral for building robust and economical networked, multi-processor embedded systems.

Objectives

� Learn about the range of MCUs that have CAN peripherals and how they fit into the wide range of devices that Renesas offers.

� Get details on M16C CAN MCUs, which are excellent choices for embedded system applications that apply CAN technology.

Content

� 22 pages

� 3 questions

Learning Time

� 35 minutes


Why Use CAN Technology?

� Controller Area Network is an increasingly popular 2-wire

(twisted pair) serial-bus communication method that is:

� Reliable (delivering error-free communication)

� Economical (having low wiring and hardware costs)

� Scaleable (allowing easy expandability with low node-connection costs)

� Available (providing many MCU choices with off-the-shelf tool support)

� CAN is an ideal design choice for systems that require:

� Low cost

� High noise immunity

� Fast communication speeds

� Excellent flexibility for accommodating configuration changes

� Compliance to international standards

� A quick time-to-market

� A relatively long product life cycle and long-term support
