a quick question about PICs

[ingrowing_whale]

Hello,

I just need to know, why are most circuits made with logic gates rather than a pic. Is it because using a PIC would be like using an A-bomb to kill a fly? overkill?

thanks alot

In some cases yes. There is the cost issue involved (i.e. time, programming, equipment, skills, parts, etc.) And in some cases depending on the age of the circuit the PIC and other uC may have not even been availible.

Hehe, it isn't a bad idea actually. An A-bomb will wipe out the fly you're trying to kill and all the flies within the nearest 100 sq.miles. Draw your own parallels.

Yeah, sometime a PIC is an 'a-bomb' approach. In general though, most digital circuits are now implemented primary by computers. (PICs and AVRs are computers).
PS. 'ingrowing whale' is an insanely funny name

First there was Logic (chips).
Then, there were PALs, then FPGAs, then RISC PICs.
Each served the purpose of reducing the size/number of logic chips on a pcb.
The RISC PIC is a "state machine" that can function as *"descrete" logic* AWA acting as a "cause & effect" machine.
Sorry for soo many quotes   
For more on the accronyms, see Google 
Another term to look up would be "glue logic"   
BTW, PICs are consdered "microcontrollers"
