I2C-bus –parallel vs serial
Commonly described as “Two-wire bus”
One wire for data, one wire for clock
Serial bus to conserve pins (versus parallel)
Master-Slave hierarchy for simplicity
Good for low to medium speed applications (< 1 MHz)
Logic

CC
I2C = Inter-IC
Parallel
Costs EMC, interconnects and pins
Lot of programming
Lots of wires
Saves PCB space
Easily expandable
Better results, no hassle
