But really, the answer to your question all depends on what you want the
data for. Are you looking to serve a market with tools, compilers,
services, etc. or are you planning a new microcontroller introduction? Are
you looking at competitive or non-competitive cores and markets? You have
to treat the 8051 separately because it is less an 8-bit product, rather,
it is a separate market segment. These are all important issues.

Thanks for your input Bill. I want the information simply to satisfy my
curiosity. Are there really more PICs made a year than 8051 derivatives? Or
does Motorola still head the 8 bit pack. It is said that more 8 bitters
are used in Japan than anywhere else - so how many and what type? Just how
many of each are made? How many AVRs etc etc? What proportion (by number by
value) is the 8, 16 and 32 bit segments and how have these changed over the
years? and so on. The last publicly available data for rough market
breakdown is for 1990 to 2000 and is:

Hi, Ian!

First, let me tell you what I've been telling companies for the past, oh, eight years:
"The death of the 8-bit microcontroller has been greatly exaggerated".

Now, Microchip leads the pack in 8-bit, both literally and in spirit. Japanese
manufacturers prefer Japanese uC suppliers. The 8051 market saw it's first hit ever with
ARM's acquisition of Keil, as ARM's own public analyst statements clearly show that
their strategy is to move 8051 users into ARM. I'm seeing very strong growth in embedded
16-bit because 16-bit has more processing power than 8-bit, and lower power than 32-bit.
That's why TI's 16-bit MSP430 is such a strong performer in the marketplace.

I'm presently working in an accurate analysis of the present market to be posted on
Microcontroller.com, but it won't be ready for another month.

BTW, whose figures are those above?
