Re: 8 bit microcontroller market

Hello Jim,


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.

Yes, they can punch that, and it's probably single sided.


I have seen it with traces on both sides. But only if they have to.


There is a reason why smart companies like TI brought their new 430F2xx out in DIP. Hobbyisist are most certainly not the reason.

One thing that surprises me, is the number of new PC motherboards that use thru-hole electrolytics. I know SMD ones are expensive, but
I'd have expected the motherboard makers had enough clout to shrink
the difference. It seems they prefer the leaded ones.


Motherboards need through-hole parts anyway for the connectors so they will always have a choice. As long as through-hole caps are only a fraction of a cent less that's what they'll use. I guess computer design is rivaled in cost-sensitivity only by automotive and consumer electronics. But it can be fun to ponder how to replace a FET with a bipolar transistor (yes, Yuriy, here cometh the 2N3904...) just because that saves 1.5 cents off the BOM budget.
