Re: 8 bit microcontroller market

Hello Jim,


It would be hard to create architecture worse than x51 today. Limited stack, single pointer, three different type of data memory, no thought at all about high-level language, 12 clocks per cycle, etc.
By any rules it should be dead long ago...

Of course, with a clean slate, and a huge amount of hindsight, and a shift of the target goal posts, with new 2006 processes and design tools, then it's no real surprise a different answer would result.

You could say the same about almost any processor, the Pentium included.

Just one tiny problem: the real world is not a clean slate, and there
are huge amounts of IP and training invested.


Fully agree. The other tiny problem: Mankind wants to be able to buy $9.95 thermostats, $19.95 sprinkler timers and whatnot at the stores. A big ARM processor or a fat DSP ain't in the cards there. Many things have to be produced in China for a grand total of a couple Dollars or less.


Include that, and the 80C51 has a long life ahead of it still.


An so do discrete parts. Look at "modern" TV sets: Many use non-SMT parts because they wanted to save a few cents on the circuit board and consequently chose, ahem, (Yuriy, close your eyes now) the good old phenolic board. There is a reason why smart companies like TI brought their new 430F2xx out in DIP. Hobbyisist are most certainly not the reason.
