Your design is nearly complete, but a nagging timing requirement has suddenly cropped up. It might call for a variable frequency oscillator, a low frequency timer, a pulse-width modulator, a controlled one-shot pulse generator, or an accurate delay. Regardless of the requirement, you need a quick, reliable, stable solution—there is no time to develop code for a microcontroller. You could build something out of discrete components and a comparator or two, or maybe the good old 555 timer could do the job, but will the accuracy be there? Will it take up too much room on the board? What about time to test and specify the bench-built timer?
