Surely a microcontroller is just a 555 with a few extra transistors?
For suitable (large) values of 'few'?
Actually I can think of many differences...
Firstly, the full equivalent circuit of the 555 is in the datasheet.
So I can predict how it should behave under all conditions (there are
many things you can do with a 555 besides astables and monostables). I
have never seen an equivalent circuit, or a gate level description of
a microcontroller.
And if you like to "tune" your ne555, you can do it on your own:
