I see this part used frequently in forum. Ever need one that does more than 10 outputs, say 16, 32, or 64 outputs ? Or
anything in between like 27.....?
One that needs an enable, or a preload ?
No code design !
Here is one for 16 outputs, easily modified to add above features. Only uses small fraction
of chip. Clock accuracy if you use onchip clock +/- 2% or better depending on your
choice of speed. Of course use a Xtal and << 1 %
Just drag and drop library components (component is onchip resource) onto canvas, wire
up to each other and pins, right click to set parameters, like frequency, counter / mux size
and hit the build button.
Note right hand column, chip resources used/left, most of chip unused. Like all the analog stuff,
the more sophisticated stuff like SAR, DelSig, DAC, OpAmps, PWM, Timer, LCD, DSP, DMA.......
Other CD4XXX chips can be realized this way as well......
