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

General Features of M16C MCUs
Platform
Best price/performance – for 16/32-bit CPU capabilities
matched to needs of applications
Versatile
Packed with peripherals – to minimize external
components
Broad
Extensive flash and package options – for storage
from 4KB to 1MB, packages with 20 to 144 pins
Powerful
Fast execution, high C code efficiency – for fast
response using less memory
Compatible
Pin, peripheral, and code compatibility – to allow
one PCB design to accommodate different MCUs
Efficient
Balanced power/performance – for systems that
perform well using less power
Quiet
Unmatched EMI/EMS characteristics – to work well
in noise-sensitive and high-noise environments
Easy
Excellent development environment – for shorter design/
debug cycles that get products to market quicker
