The only issue with the 555 in volume is the cost of the external parts (caps and resistors) to make it work. Some micros with built-in oscillators will actually result in a lower total part count, making the board cheaper.
- sagacity 16y agoJust so that we all know, are you saying this from a (strictly) commercial perspective, or from that of a hecker's? What 'board' are you talking about?
- nzmsv 16y agoCommercial - by cost/board I mean the cost to assemble a PCB. Placing each component has a cost, even when done automatically, especially since that (probably unique) cap is another type of component in the set-up stage. But I'm just a student and haven't actually ever produced a PCB in volume. But even for a hacker fewer components mean easier layout and assembly. Not to mention that the timings generated by a micro are much easier to tweak.
