Depends on your requirement :)-
we can separate them based on Clock in the following way.
1) I2C & SPI are Synchronous Interfaces & used on PCB
2) CAN is Asyncronus Interface & uses wires for long
distence communications.
Diff B/W I2C & SPI:
1) a)I2C is invented by Philips
b)Invented by Mototola
2) a) Used to interface with Audio/Video Devices as the
philips is expertise.
b) Access High Data trnsmission deives like EEPROMS
3) a) I2C Supports Speed is :100Kbps(Standard)
:400Kbps(Fast)
:3.4Mbps(High Speed)
b) SPI Supports : 3Mbps to 10Mbps
4) a) I2C is multi-master, Address based Communication
b) SPI is Master Slave, With Slave select(SS) based
Communication
5) a) I2C needs 2 pins
b) SPI needs 3+n pins (n is no.of devices)
6) a) I2C supports 127 devices
b) limited by avilable Chip slects
Coming To CAN:
invented by Robert Bosh
supports 127 devices , multimaster , Message based
comminications, Reliable, supports 40kbps to 1Mbps
