What are the Correct Figures?

Charles,

The market share figures for the 8-, 16-, and 32-bit microcontrollers add up to 111%!  They should add up to about 99% to allow 1% for 4-bit microcontrollers.  What are the correct market share figures???  According to www.atmel.com/Images/45107A-Choosing-a-MCU-Fredriksen_Article_103114.pdf, the 2014 figures are:

8-bit:  40.3%

16-bit:  21.9%

32-bit:  36.9%

Although not mentioned in your article, I suspect another reason that designers stick with 8-bit microcontrollers is to keep designs simple and avoid the additional complexity of 16- and 32-bit architectures.
